mplayer ~/mpc2/samsung_t20/home/michael/videos/310058.avi -lavdopts idct=14 -vo md5sum
mplayer ~/mpc2/samsung_t20/home/michael/videos/310058.avi -vc xvid -vo md5sum
310058.avi uses mpeg_quant, qpel and gmc

md5s match so theres no difference between lavc and xvid decoders

files with b frames have different md5 sums ill try to figure out why
