I've installed K Lite Mega Pack 13.1.9 and I tried to play a DVD, and the following error pops up in MPC-HC player. Daum Potplayer plays it but the video is somewhat garbled and there is no sound. VLC plays it alright thanks to its internal codecs.
I had Windows Media Player disabled. I've re-enabled it but it didn't solve the issue.
I've installed ffdshow as a separate installation and it didn't solve the issue.
Windows 7 Pro, Intel(R) Pentium (R) D
