If you missed the discussion, Microsoft does not install all codecs for us. While http://www.moviecodec.com has most codecs, don't just install all you can find. You can imagine many reasons why this is a bad idea.
The scenario: I goofed on a new HD install, panicked when I couldn't get the O.S., so I used the recovery disks, which brought it back to my original O.S. (Me) on the new disk. Then, upgraded to XP, and began the arduous task of trying to return things to where I left off.
System: 1.3 GHz, 768 Mb RAM, 250 Gb HD, Pavilion 9870 PC, XP Home, WMP 10
Before this disaster, I was able to play the video clips, which included mpegs, avi's, etc.
But, some of them won't now. I've been reading many of the posts here. It sounds like this topic of codec may be my problem?
the moviecodec site is the place I need to go?
It was WMP 10 that was working before, but it doesn't play all of the clips now.
I must have erased some of these codecs?
