Hello,

From: Attila Kinali <kinali@gmx.net>

Thanks for forwarding this - I've lost track of how man MPlayer mailing lists there are ;)

Can someone see what's wrong here ?

Another couple datapoints that might provide additional information. I've several DVDs that exhibit the behaviour that mplayer has no trouble with but mencoder either stops short or can not start at a later chapter. Last night I was able to transcode chapters 2-4 to divx with: ----- #!/bin/sh rm -f frameno.avi mencoder -v -dvd 1 -chapter 2-4 -vop scale=640:480,crop=704:472 -sws 2 \ -oac mp3lame -lameopts vbr=3:br=128:q=4 \ -ovc frameno -o frameno.avi mencoder -v -dvd 1 -chapter 2-4 -vop scale=640:480,crop=704:472 -sws 2 \ -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2500:vhq:keyint=150:vpass=1 \ -oac copy -lameopts vbr=3:br=128:q=4 -o title1.avi mencoder -v -dvd 1 -chapter 2-4 -vop scale=640:480,crop=704:472 -sws 2 \ -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2500:vhq:keyint=150:vpass=2 \ -oac copy -lameopts vbr=3:br=128:q=4 -o title1.avi -------- But if tonight I tried to finish the movie (chapters 5 and 6) using "-chapter 5-6" I get the error: ============= Sorry, this file format not recognized/supported =============== === If this file is an AVI, ASF or MPEG stream, please contact the author! === Cannot open demuxer There are according to the initial messages 11 chapters (in 1 title) on the DVD (2 movies, one movie is chapters 2-6, the other is 7-11, chapter 1 is the obnoxious FBI warning that makes you feel like a criminal for watching something you own): Reading disc structure, please wait... There are 1 titles on this DVD. There are 11 chapters in this DVD title. There are 1 angles in this DVD title. DVD successfully opened! Very puzzling. I know the DVDs aren't the highest quality (4 movies on a 2 sided DVD for $10) so the mastering probably isn't the best but MPlayer has no difficulty playing the discs. Thanks for any insight as to what might be going on. Cheers, Steven Schultz sms@2bsd.com
