ive never heard of such a pack. what does it do?
It contains a set of video and audio codecs that are popularly supported:
Video:
XviD
H.264
MPEG-2
Audio:
AC3
DTS
DTS-HD
Vorbis
You should be able to play a lot more content on Windows Media Player as well when you install CCCP. If you want to uninstall this software at a later date, all of it uninstalls via "one-click" by uninstalling CCCP in Add/Remove Programs.
Im confused, how will a codec pack stop the trainer from doing the "on, off" thing?
What i don't quite understand is how it can just 'happen'. It worked fine earlier in the week and I've checked the Windows updates list to make sure nothing has been installed which would affect it but nothing has.
More than likely the problem is with the way Windows handles the splitting of media files. Windows 7 has native codecs for those but for some formats Windows cannot properly split the audio from video or other data (MKV format is notorious for this).
The Haali Media Spliter from that pack fixes that.
