Hello All, I hope you can help with with this problem. I am unable to play Any AVI or XVID files on my PC right now. I can play anyother format like DIVX, MPEG etc. Everything was working fine but then I downloaded an old version TMPGenc to make a file and then after i did that none of my AVI files will play on any of my players. I reinstalled Windows Media 10 and downloaded the XVID codec but still the same problem. I really have no idea whats wrong. any thought? thanks.
