What I think it means that frame #61269 has to be an I-frame, and there should be no other I-frame until frame #61281, which is the next I-frame. This seems to be needed in order to remux a MPEG2 video stream to a valid DVD structure and to not have sync issues. >However, I'm puzzled why Ifoedit would demand fixed-size/structure >GOPs.

Definitely true, but I do not author a completely new DVD, but I want to remux the the video together with the existing (dts/AC3) streams. And with a normal m2v file (produced by either TMPGEnc or mpeg2enc) I have stuttering sound. regards Markus ------------------------------------------------------- This SF.NET email is sponsored by: FREE SSL Guide from Thawte are you planning your Web Server Security?
