i compliled a dvd that orginated from DV files with dvd-lab, played it in ps2, worked fine, my friend took it home and tried to play in his sony dvd player, and when using the scene selection to go to a part of the video, it wouldn't play, the sound would play for that part of the video...but the video would stay at the scene selection...any idea's? he could play the video from the beginning but thats it. usin ritekg04 media, and nero to burn. any suggestions are welcome.

thx, josh
