Hi there,
I have a very particular problem and I need your advise.
I am having an MPEG-2 file which shows a shorter duration than the actual movie. Been told that I need to recode it (any other suggestions to fix that?)
Is there any software that will be able to recode MPEG-2 to MPEG-2 in order to fix the probelm?
If I recode the 1.1gb file into VSO, the file will grow to 4.4gb. I'd prefer to burn the MPEG files directly onto the DVD rather than convert them into a larger file and lose space.

Maybe this is only the guilty of the playing software. If the file is A/V in sync, why would you like to lower the quality of the movie by re-encoding it?

Would the quality suffer if I re-encode it and end up with the same file size???
the problem is that if I burn the MPEG-2 file as it is, it will record as much as the indicated time. Bear in mind that the movie is running for longer than indicated. All I need is to sync the displayed time with the actual length of the movie.
Any ideas??

Probably the encoder cannot understand the VBR audio file and shows only the length of the 'CBR' stream.

Is it so necessary to have VBR audio?

Yes, re-encoding always lowers (much , or of a negligible amount) its quality. Only multiplexing keeps the quality =.

A suggestion: use old 224 CBR MP2 and stick with it (maybe your player can also understand higher bitrates. You can usually raise up to 448 kbps , and a 448 CBR MP2 audio is much better than a 128 VBR MP3 one). I've seen 128 kbps CBR flawlessly-speaking movies.

In movie-encoding, it's 'keeping high the Video quality' the main objective.

Moderator,
you are very helpful to me today and I have to thank you for that. I am not sure, but I think i have CBR for the entire file. See, I have bougth a DVD recorder to record tv programmes on DVD-RAMs, I edit them directly on the DVD player and then copy them onto the HDD. The file is in VRO format. When I rename the file into mpeg and play in into any media player, the time is shorter than the real duration. This is not a problem per say but when I burn the file, I end up with a fraction of the movie.
If a encode directly from VRO to VSO (through TMPG) is the file going to get bigger (haven't tried it yet)?
