When i play the mpg file, it is 55 mins. but when i burn the mpg to svcd and i play the svcd, it it only 40 mins. Is this right?

Do you mean on the DVD playback timer, actual playback duration (as in the movie goes too fast), or do you mean disc space?

If it's the DVD timer (says the movie is only 40 min long), this might just be a quirk on your player. I know if I don't author with VCDImager, timecode gets screwy on my player too. If playback isn't compromised, no problem then.

If the movie is playing too fast... you said you tried for an SVCD... is it at the proper framerate? Remember, if it's 23.976/sec, you will need to add pulldown to the video stream to make it play at 29.97 (I'm assuming you're NTSC). You won't need to re-encode, just use pulldown.exe on the video stream only (this tool should be available at the left).

If you mean disc space, it just means you used up to the 40 minute mark of SPACE on the disc. For standard VCD's and CD's, the space is measured in minutes... so if you used a low bitrate for your SVCD, its' possibly you only used 40 minues worth (or about half) of the disc.

BTW, I think "SVCD Scan Offsets" use the "time on the disc" reference instead of the actual playback time... so a 800MB SVCD could be 60 minutes in duration, yet take up 80 minutes of time space...

Hope I covered everything.
