Embed Xvid codec into CD/MPC? (prevent any software installing)

This is for a non-profit info CD. We were thinking of encoding the video with XViD. The simplest "pop disc in, don't install anything to play video" option has been MPlayer and simply performing a simple batch "mplayer.exe video.avi". However, if I recall that mplayer borders on illegal, due to all its decoding abilities of licensed codecs. I was wondering if it was possible to play Xvid videos with MPC instead, somehow embedding the codec on the disc itself, and not requiring the user to install anything to play it?

MPC can load filters dynamically. Should work with just xvid.ax and xvidcore.dll on the CD and loading xvid.ax. Something like: mplayerc.exe /filter xvid.ax input.mp4 Xvid is MPEG-4 which is licensed and with mplayer/libavc you can disable decoders if you wish.

Why not put MPUI plus a generic build of MPlayer on that CD? You can also use the nice Autoplay feature of MPUI :D For MPEG-4 decoding you won't need any additional (proprietary) Codec/DLL files. Just MPlayer.exe itself.

i created a Eltorito bassed Bootcd for Standalone Playback purposes a while back under DOS im gonna release that soon maybe it's what you searching for it's a small bootsector you have to burn on your cd you just put it in start the pc and it boots right into the Movie :)

He might have been referring to the lack of mpeg-la (and other) decoding licenses.
