HAve just installed xp pro on my new system and have been playing around installing codecs.
Installed divx 502 bundle
Installed nimo codec pack
Now several divx play audio ok but no video (read could be problem with xp media player - beta 9 fixes this)
But, in the process of this I appear to have corrupted/removed the codec which plays back standard mpg,m2v video.
Tried tmpgenc'ing a file and playing back and get "filetype not supported" both with a combined mpg audio+vid and just m2v video
New to xp, how can I check a codec, completely remove or reinstall again (tried reinstalling meda player - not working )
