I can no longer play avi files?

[lerxst]

For some reason I can no longer play avi files. I only get audio played but not video. I tried this with Windows Media Player and with Nero ShowTime. Both of these applications used to play video+audio fine before.

Could it be something I installed that messed things up?
How do I restore it back?

I will appreciate any info regarding this.
Thanks.

try grabbing another xvid codec and installing, use google... or try using system restore if you're using xp to try and fix the problem.

get gspot and it will tell you what codec you need

[waheed]

re-install your codec.

better still, use media player classic

re-install your codec.

Both very good suggestions.

All you pretty much need for "playback only" is ffdshow. I use WMP10 with no problems what so ever.

Thank you all for the suggestions. I did search for the missing codec and found this guide to do this (in case anybody is interested): http://www.moviecodec.com/topics/318p3.html

It worked perfectly well.
thanks.
