How to do Multiplex

[dduong]

Hi,

I tried the evaluated version of MPGVCR and TMPGEnc, But I have a problem to multiplex the Video and audio. I demultiplex first
and multiplex the .mpv file with mp3 and it can't be opened by Window media 9.
Do I need to do demultiplex first? and Why do I need demultiplex?
I tried to burn it by Nero but it showed the error with incompatible audio.
Please help. Thank you

sounds like the mp3 (at least) has an error with it. Could you post the specs of at least the audio to see if there is something up with the audio.

you could, convert the mp3 to a wav file and the mux that with your video.

What are you trying to play this on? Settop? PC? Both?

Maybe it's a typo, but if you didn't know before, MP3 is NOT part ot the DVD spec, so there's no way most standard settops will ever be able to use the file, no matter how it gets burned.
Also, Nero & most other DVD authoring & burning apps, won't accept that file (either muxed or demuxed) as sources for DVD. They know better than to even try to use that filetype.

If your file is truly MP3, you can mux it and use it ONLY in Windows Media Player (or one of the many variants) on the PC. I have successfully Muxed an MPEG (both MPEG1 and MPEG2) with mp3 audio strictly for use on a PC.

Otherwise, you want to take your MP3 and decode/re-encode or transcode to one of the APPROVED DVD (or VCD if you lean that way) formats:

AC3 (aka Dolby Digital)
MP2
Linear PCM (as generally used in WAV files)

This will mux correctly and be burnable and playable.

HTH,

edit--I said "most settops" above, because there probably are a few that will play mp3-muxed MPEGs via simple ISO file playback, and maybe a rare one that is so forgiving that it doesn't care what format the audio payload on a DVD is.
