I’ve wasted money on this site and I’m not happy! I pay a subscription and am then told that the video playback doesn’t work! POINTLESS!!!

Even loaded the K-Lite Codec Pack 19.12 Beta.
Still cannot compile the vcd.
I think have to pay first.
Problem is they mention clearly that pay before you use!

This codec pack is completely free to use, no payment required.

It's not free! Doesn't work unless you pay.

I have never experienced this and I have been using K-Lite Codec packs for over a decade. I think you have downloaded a dodgy copy from somewhere.

after install it , can't convert anything with jetaudio player, probably the LAV codec again, how to disable it?
Reviewed on K-Lite Codec Pack 12.3.6 beta
Lav has a blacklist option in the registry. Ask on K-Lite forum for help.

This Codec Pack has all what you dont need. Some Toolbars and crappy other software.
With this codec pack i have more trouble as without it.

Why does it install AVG toolbar and Chrome?
Why is Chrome hidden from Windows explorer but not from the command prompt?
Is this some kind of rootkit?

Because you dont read when you are clicking Next or OK... Thats why.

I`m pretty sure this won`t be published but wanted to send you a heartfelt "up yours" for including the nasty piece of software called "babylon" with this install -
Even though I very carefully de-selected all the additional junkware attached to this install and SPECIFICALLY excluded "Babylon" - your installer STILL installed it, and it is a BUGGER to remove.
I do not want my surfing habits sold on to a third party and neither do I want this trashware hogging my processor time sending that information to god knows what shady people so After a long search removing it from my machine , registry and browsers I will not be using your service again and be taking strenuous steps to prevent anybody else making the same mistake.

Sounds like you got a shady copy I have been using this for over a decade with no issues.

Bad! Very bad! I was using v8.3.0 Basic and everything was excellent.
Then I've downloaded v8.6.0 and that was disaster.
My MKV files were "screaming" in Windows Media Player 9/WinXP SP3.
Please, fix it asap.

This app has become completely useless for 70% of the people because MPEG-4 encoder (along with 90% of other useful encoders)in FFdshow VFW is GONE! For f@ck sake leave it as an option... I guess You don't want users to do their encodings anymore.
In the last 3 months everybody I know has said farewell to this codec pack because of this single flaw. Good luck with it...and btw, FAREWELL!!

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!!

bad codecs, ever since i installed them ive got audio problem on pc, i try uninstalling but it seems it changes settings,
the problem is lets say i want to listen music
where a band sings [ more than 1 person],
well the music and the singer on main mic will hear with normal sound, while all others singing behind will hardly be hard [ i had to turn speakers to maximum to hear them].
well the problem is you cannot fix that by uninstalling codec, the only way i could do it was reinstalling windows xp.

This masterpiece does something which is rarely seen nowadays: IT CAN F**K UP A FRESH WinXP INSTALL completely just by installing it using the default settings.
"Clean uninstall including registry cleanup is a major feature" they say. However after uninstalling this "state of the art" pack and installing my favourite ACE MEGA CODECS Pack 6.03 (which is heavily outdated that's why I tried to find a replacement) surprise: ACE is not working as well... This m*f* screw up something.
gotta go to reinstall windows again...
