K-Lite Mega Codec Pack 20.1.0 Final

Have been using for years. Great Package!!
I found a problem in the recent versions up to current with getting an error "Incorrect BASS.DLL version (2.3 is required)" when playing *.aac files only (playback is OK once you dismiss the error message).
The library for bass_flac.dll is version 2.3 and needs to be updated to 2.4 to work with aac files.

Download : BASSFLAC 2.4
From : http://www.un4seen .com
File Need: bassflac.dll

Copy to : C:\Program Files\K-Lite Codec Pack\filters
Delete old : bass_flac.dll
Rename : bassflac.dll to bass_flac.dll

All versions since 3.95 have worked fine for me; in this version a problem with Media Player Classic - takes too long to start or doesn't start at all (with FLV or AVI files)
thats right

first of all thanks...
This is the best codec pack available for daily or normal use. U cant get more satisfaction by any other software as u get from this..

Working great. Vista 64bit Phenom 9500 4core. No issues on full screen on any player.

@se7a:

Change the video renderer in MPC.
options > playback > output > DirectShow video

@Charon:

- Update to the latest version of the codec pack.
- Check if you haven't accidentally enabled the MUTE button
- Change this setting:
options > playback > output > audio renderer

having the same problem as John Doro,my videos aren't playing in fullscreen with media player classic.Windows media player,VLC,and WinAmp running in fullscreen with no problems.I installed older video card drivers and same thing,so I know isn't the drivers

@zonk

K-Lite Mega Codec Pack 4.1.4

All versions since 3.95 have worked fine for me; in this version a problem with Media Player Classic - takes too long to start or doesn't start at all (with FLV or AVI files)

You don't need the DivX codec. Thumbnails work fine with ffdshow, which is what the codec pack uses by default.

I just found out that my problem was not caused by xvid codec in the package. It turn out to be DivX codec (maybe), when windows explorer try to preview avi files that contain DivX video in it. There is a 3 way to avoid the explorer.exe error that I found on the net.

1.regsvr32 /u shmedia.dll - avi file no longer have a thumbnails.
2.HKEY_CLASSES_ROOT\\SystemFileAssociations\\.avi\\shellex\\PropertyHandler - Delete the "Default" value. (Backup first) - avi file have a thumbnail but disable summary in the properties. (You can use mediainfo)
3.Download and install DivX Free 5.2.1 - avi file have thumbnails and summary like normal.

Honestly, I don't like all that solution. I like my avi file to have a thumbnail preview and summary. But I don't like to have to download another codec package that have the same codec file just to solve one problem.

I hope in the next release K-lite Mega have the solution like in the DivX Free 5.2.1. K-lite Mega is my one and only choice. I don't want to use other.

@Naps

Your problem can be solved by removing the Xvid codec that is (improperly) installed on your computer.

@sunil

There are three solutions:
1) Use the older version of MPC (1.2.1008) that is included in the pack.
2) Select the standard EVR renderer in MPC options
3) Disable DXVA

@Simon Lin

That error was fixed in 5.4.4

Amazed on how many problems I am see by others.
8 comps running K-Lite Mega and no issues. Everything from XP to Vista 64
What I am seeing with many of the problems listed is most likely the same issues.
1. Never overwrite old version.! Uninstall
2. Never have more then one Codec package.

Here really is the best way. Uninstall all other codec packages. Run a registry cleaner if you had other version then K-Lite.
Reboot and install.
