KMPlayer + K-Lite Mega Codec pack = the best!!!!!!!!!

why?
can play anything AVI, RMVB, RM, OGM, MKV, FLV, XVID, MPEG, MOV, etc
full screen in high colored quality (kmplayer beats media player classic with this)
adjustable screen size, increase width, height removes the black part in DVD videos
many media filters and rare video/sound filters (media player classic dont have this)
adjustable video brightness, contrast, color, etc..
many features that you cant see in any player..

try it and compare hehehe
