Does anyone know what codec I need to play an AVI file in WMP for Vista? I used FFDShow with WMP 7.x, but that conflicts with Vista for some reason (their last version was in 2004). I can play AVI's with VLC media player, a nice free download, but would rather use WMP. Thanks.

You can download some codec's here >> (http://www.free-codecs.com/download/Codec_Pack_All_in_1.htm)

I like VLC Player very much, it'll play anyhting:
