I am just using the standard bitrate: mencoder -oac mp3lame -ovc lavc -lavcopts vcodec=mpeg4:vhq -o <output file> <input file> The codec that my friends are using to play the video is the standard free divx from divx.com. Charles

Hhhmmmmmm.....nothing special.......I am using following multipass formula: mencoder -oac mp3lame -lameopts vbr=3 -aid 128 -o frameno.avi -ovc frameno vts_07_1.vob mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vpass=1:vbitrate=1500:vhq:v4mv -vop scale -zoom -xy 720 vts_07_1.vob mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vpass=2:vbitrate=1500:vhq:v4mv -vop scale -zoom -xy 720 vts_07_1.vob Maybe i have here some parameters, who makes this uncompatibility with Windows players..... I will try reduce these parameters to be "minimalistics"......here is maybe way. Thanks for forwarding my mind process. (-:
