If I had any hair I would certainly be pulling it out about now.

WMP plays all of the file types that you would expect it to, including DVDs,
but will not play MPEG-2 files. I will swear that WMP and Media Center
have played MPEG (MP-2) files in the past. In fact, I think that I remember
having to install the Vista codecs to get them to play properly. I can
think of nothing that I have done that would change that. Every other video
application that I have plays them just fine.

Since discovering that WMP no longer plays them I have removed the Vista
Codecs -- would not play MP-2. Re-installed them -- still wouldn't play
them. I have removed the Vista codecs and installed the K-Lite codecs but
they still won't play.

By won't play I mean, the picture is just a bunch of horizontal lines though
the sound seems ok.

Thanks in advance for anyone's help with this.
