Windows Media no longer play videos after update

Hi, I just upgraded to 6.1 and ran it for a week or so.
I just notice yesterday that after upgrade, WMP won't play MOST of my videos anymore. I have like 50+ clips on storage card, and WMP only plays maybe five or six of them. I browsed the video folder using "pictures and videos" and only those five or six showed up.
What's the cause of this? I tried rebuilding my library but that does not work. This problem does not occur when I upgrade from WM 5 to WM 6.

do the files still exist on the card, but not the media player/ or does the card not have the files any more/ or have the files become corupt (possibly flashed with the card installed)
I ususaly use a different player for vids because WMP does not support a lot of codecs.
Look for TCPMP on google. that will play almost anything, and you can install codecs for it.

the files exist on the storage card, even the movies list showed up in WMP's library (50+ videos in WMP library).
but when I click on play, wmp keep skipping to the next track, something like it recognizes the file type, but cannot play the file (as weird as it sounds, that's what happen) . Some videos still played ok though (5 or 6 out of 50+).
When I opened the video on WMP on previous ROM (WM 6) they all played ok.

The OEM packages used by some to cook ROM's are missing either files or registry settings. I use an OEMAPPS package that includes all the related files and registry settings from the AKU 3.3 T-Mobile ROM, Lockstream DRM files and registry settings excluded. I don't know exactly what needs to be fixed, but it's one of those two things.
