How do I made it so VLC plays a movie with the xvid codec?
No offense intended but may I recommend you try Combined Community Codec Pack?
It supports most known formats and you can get a Realplayer and Quicktime plug in (Real Alternative and Qucktime Alternative though QT alternative has been pulled due to a lawsuit from Apple its still available at many websites).
I used to run VLC and several toehr players to do everything but all I use is this and the two plug ins t play pretty much everything. I still sue Winamp for audio cause I like its playlist editor.
EDIT: See if you can d/l FFD plugin for VLC. It is suppsoed to support Xvid
Free-Codecs.com : Download FFDShow MPEG-4 Video Decoder 2007-07-31, FFDShow MPEG-4 Video Decoder 2007-07-29 MMX and FFDShow MPEG-4 Video Decoder 2007-07-29 SSE : FFDSHOW is a DirectShow decoding filter
Thanks man appreciate it : )
