Folks! All of you who have problems with these codecs and codec packs do the following: install Shark007 codec pack which is compatible both with Windows XP and Vista or its Windows 7 version that is fully compatible with Windows 7 which you can download from many web-sites.

I tested this codec pack in all of these three Windows versions and there were no problems and conflicts. Uninstall all related single codecs and packs and install this one and you will be able to play all audio/video formats in almost all popular players.

Only that you need is to configure it correctly and you cannot make mistake. Just don't forget to set almost all video formats Gabest and ffdshow wherever it is possible.

@jerome

You need to use the Mega pack, which contains x264VFW for encoding H.264, encoding with ffdshow is no longer possible.

I like k-lite, but I've an issue with the 6.7 FULL pack for encoding : in the virtualdub conversion menu > ffdshow, the H264 encoder is not listed in the ffdshow.. ?

I installed 6.7.0 Full version. It is still a little bit slow. Especially when opening wmv files. I think it is about Media Player Classic. Windows Media Player loads the files far better. I don't know if I should tweak something...

Version 6.5

I can play all video as normal but there is no sound

Totally mute, no matter what I've tried.

I'm having problems with subpicture buffering in this version. Before it went smoothly on 3 subpictures, but now it's terrible (even SD videos are jerky) and I have to keep it on 1 although that setting screws up all the fancy subtitles.

well it's handy n good one

whatever, i've got problem with FLAC sound. The solution just to turn it on in ffdshow audio menu.

For WMV problem, that not play smoothly.
Just try to change the playback>output in options menu. Try the VMR-7 or VMR-9.

The pack is awesome but last two versions are too slow. I re-installed 6.20 for a better performance. Everything is OK now. Please make something for the next release.

Thanks.

Hi, I've just installed the k-lite codec 6.40. However, it seems to be a little bit slower (not smooth with small lag) than 6.20 while playing video.

I reinstalled the version 6.20, everything works fine again. I experienced the same issue with version 6.30.

Could anybody tell me why? Btw, I'm using Win7 32bit system.

Why stop supporting rbmb format? You've already left QuickTime behind some time ago. The big advantage of this pack is compatibility of different formats, but now you are abandoning them one by one?

K-Lite Codec Pack 6.2.0 Full

this is simply the best codec pack available.it took me hardly seconds to overcome the problem of player different files in wmp 11.

well, i've installed v6.20
i realized something different about this version installer
it has no option to generate thumbnail preview for real video format (rmvb and rm). I think there's no problem with that since i dont use thumbnail preview too often since it may be lead to explorer crash but when I opened a real video format, my mpc and wmp cant open this file. They said i don't have any codec to play this format

this version can't play real video (rm or rmvb) anymore, how disappointing....

I recently bought a 1gb Intel N270 crappy netbook to get to grips with PC's (the first I've ever owned, but definitely not the first I've used). I wanted a machine to seriously abuse and to see how much I could squeeze out of how little.
I'll get to the point; I'm a movie, music and games fanatic, and I have to say this has helped improve my experience of video and sound quality immeasurably.

-----Quick Review - Read This-----

I honestly don't think that unless I shed out some serious cash on some dedicated hardware, that I could possibly improve upon the viewing and listening experience I've had with this AWESOME codec pack. That said, it does take some setting up, such as disabling one or two Windows Media Player update-type annoyances (Google for how), and, much like other specialized software, has a mountain of options, some of which can have undesirable results. On the upside, the majority of important options have additional information when hovering the mouse pointer over them, and are highly useful if you don't want to go thingying comething up!
So if you absolutely must have superior video AND audio playback (I've switched from VLC to this after about 2 days!), then this was made for you.
On the other hand if you just want good video and audio quality, stick with Internet Explorer for streaming (no, really - I've tested against Firefox, Google Chrome and Opera for video streaming - it's very very good indeed and almost as quick as Opera to start up - get divx, flash and any other plugins/addons that you come across as missing and you're sorted), and for audio and offline video and ease of use, VLC.

-----Further Info-----
If you do get any problems with file formats not working in K Lite, just try disabling them in the options and possibly re-set the previous player as default (Google again, if you're not sure).
That's it - it's 6:30am, I wrote this review listening to Beethoven's Symphony No.7 Movement 2 Allegretto, nearly wetting myself that it sounds so good. I HAD to write a review, just to get it off my chest how good K Lite really is.
No need to give this any marks - it's brilliant,
though it does take some setting up initially.
-Video and Audiophiles - this is what you're after!
-If you just want good quality playback without too much fuss. try VLC or look into optimizing your current player (the magic of Google, again).
Night all!

Visit the support forum for help.

Third party decoders such as CoreAVC can cause explorer crashes.

I have used K-lite codec pack for long and its good but this latest version is causing my windows explorer to crash whenever I open a folder with MP4 files. I think there's a problem with the MP4 thumbnail generation. There's no problem with other formats. Please fix this bug.

Long time user of K-lite standard, always working fine here... thanks for your work.

The 5.9.x version (including the update) has a problem when trying to play m2ts files using media player clasic! The video speeds up for no reason and the audio is full of stutter. Had to change back to the 5.8.3 version.

I've enjoyed K-Lite for a long time but I had to get rid of this latest Media Player Home Cinema crap. Crashed much too often and would sometimes play a file one day but not the next. Then there was a big crash last night that froze my computer completely.

The other thing that troubles me about the new Media Player is constantly trying to control other programs I have running. There is no need for it to do this. I had to close all programs and windows to play a video or I spent two minutes blocking requests from Media Player via my firewall.

That's how malware operates. not saying it is malware but I have not other programs outside of security which needs some much access and control of my computer.

Going back to previous version. I hope these issues can be resolved.

IS THE PROGRAM GOOD OR NOT?!
THESE REVIEWS ARE CONFUSING ME!
I'm deciding whether I should download this program or not, I heard that there's tons of issues. I heard that this program is excellent.
OVERALL, IS THIS PROGRAM GOOD?
Oh dear, I need a codec...

@Hvati

You can customize the buttons in MPC-HC by replacing the file "toolbar.bmp". If you delete that file then you will get the old buttons back.

I like K-lite a lot but I don't like the buttons on the bottom of the newer version of MPC-HC so I have to use an older version of MPC...

it doesn't play everything but it's really good,i still have VLC,just in case KLite fails

I had a problem playing .avi compressed with VP7. I solved it by adding the specific line of subtype (MEDIATYPE_video) to VP7 decompressor through MPC in Options/External filters. It was the same line MPC reported as missing.

I'm a long time user of K-lite mega codec pack, but this version is terrible! it's full of bugs! When i try to open anything with homecinema classic, the player freezes for five seconds, then continues to play the file from 6 seconds onwards, but the playback stutters a bit. This happens for every single file be that avi, mp4, m2ts anything! I'm going back to version 4.9. which is the last stable version i've found. used v4.9 since it was released without a problem!!

Another very good codec pack is "Ace media codec pack"

I think they are not being as updated as this 1 though, but worked fine for my XP when I had that.

Pay attention if u have a 32 bit or 64bit os and get a pack accordingly

same problem as mike below, skipping audio on any movie file which contains mp3 audio. long term user of this codec pack, this is the first time i've had an issue. as greg suggested this is not a selected speaker config issue - any other suggestions? thanks everyone!

@Mike

You probably haven't set the correct speaker configuration. You can configure it with the Codec Tweak Tool, or during installation.

I downloaded the standard package just to watch movies online and the audio makes a weird scratching noise (sounds like the audio keeps skipping) along with the background music and I can't even hear the actors' voice. Anyone tell me how to fix it?

Hi, people. It solved some of my problem, but created another. I use MPC (or here I used MPC home cinema) and the player doesn't see multiple audio tracks. Only the first one. What should I tweak for the mpc to start seeing and switching between multiple audio tracks in mpeg2 files (vobs)? My previous MPC had this capability, but I uninstalled everything, when installing this new k-lite codec

For me it's perfect. I have used k-lite codec pack since 2009 and already recommended to my friends many times. The problem is some file types can't be displayed with an icon. Just like the .MKV (Matroska) format, It uses the generic picture of WMP.

Downloaded latest K-Lite Codec Pack Full so that Windows Media Player would play MP4's etc. Worked great. However now all my jpg picture files wont show thumbnails in any of the folders. All that shows is a generic picture thumbnail. I have tried various things to fix it but it looks like I'm going to have to uninstall K-Lite to try and sort it out.

Actually, I can play WMV files with Windows Media Player, Jet-Audio 7.1.9.4030 Plus VX, Real Player 11.0.5 but not Media Player Classic. Before, I used K-Lite 4.1.7 Full and everything is OK! Until I set up K-Lite 4.7.0 Full and I have such problems. I don't think "You need codecs from Microsoft to play WMV files. Those are normally bundled with Windows. Install "Windows Media Format Runtimes" and you should be able to play those files" is a solution! Thanks for reply!

@Lindsey
You can find a solution for that in the K-Lite FAQ.

Everything works fine, except for one thing. The .mov video files I added to Windows Movie Maker play, but there is no sound... the audio is missing. Can somebody tell me why this is?

Along with MPC Home Cinema this is the best media bundle available. We have been enjoying music & movies without need of any other packs. Best performance. Thanks

it doesn't play everything but it's really good,i still have VLC,just in case KLite fails

some FLV still can not be played.

@Dlucks

That is probably a bug in the DivX browser plugin.
If you want to play the files with Media Player Classic, then you need to download them instead of streaming.

@Tom Bird
Go to the codecguide forum. They should be able to help you there.

decent pack, except that when divx streams a vid from the net the audio seems to be fast forwarded at 200k percent, and I dont know how to associate firefox with mediaplayer, any suggestions?

K-Lite Codec Pack 5.4.4 Full

I have been using K-lite for years now, almost no version had a problem. I installed the latest one and now mp4 files play as audio but the video is not recognized.

What is wrong? Should i just wait for the next version?
