I prefer to use mplayer to dump it to file before using ffmpeg. I use: mplayer -dumpstream dvd://3 -nocache -dvd-device /path/to/VIDEO_TS -dumpfile output-file.mpg Where the number after dvd:// means the title to be dumped. After that i have no issues converting. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
