Which command do you use ? You could exctract them with mplayer: mplayer -vo jpeg file.mpg That will create a lots of jpeg's in the current directory. ;) But I'm not soure if you see the problem there. If the stream says that it should play back the top field from the current frame before the bottom field of the stream. And it would be correct the other way round. > In theory, i could re-create the DVD with different -z parameters in > mpeg2enc, but: > - the encoding time is enormous Just encode a few minutes. > - i'd rather not waste DVD-R's, and i'm not sure if i can test with > DVD-RW (not sure if the players will recognize the format) > > Suggestions? Test it with CD-RW and SVCD format. You should have the same problem there. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.net email is sponsored by Dice.com.
