Mac: extracing VIDEO_TS audio; replacing VIDEO_TS audio?

Worked perfect! You guys are awesome. Thanks a ton.

Nice.

I forgot to ask, were you able to keep the chapter markers and if so, did you need to use the original IFO/BUPs and if so, was it just the VIDEO_TS_IFOs or the VTS ones as well ?

This project had no menu and the chapters were arbitrary. I used Toast to multiplex the audio and video back together. It added random chapter marker. I think Sizzle might be able to add them where you want them but I have never used it.

Right, thanks for that. We'll just have to wait for a guinea pig with a menu and chapters to find out the finer details.

I wanted to bump this thread to ask a question. How would one go about this for non PCM audio? I have been working on a couple of things. One has AC3 stereo audio as the source. I have some fan commentary I want to add onto the DVD for my own viewing pleasure. The fan commentary is in MP3 format. I figure I can convert the MP3 to AIFF and import both the demuxed soundtrack and the new commentary into my multitrack software. Make sure it is all in sync and the same length (to the frame) of the origional. I would then export to WAV. I think I can remultiplex from there. Is there a better way to not recompress the footage. This is another film that I didn't keep the menu and it contains the feature only. Any recommendations?

if yer only demuxing, messing with the audio, & then re-muxing, there should be no re-compressing of the video footage

Yeah I do know that. I think you might have to use different methods (software) depending on the audio format. I have managed to make it work for PCM audio. I was bumping to ask about AC3 sources material. I ended up just letting it recompress the audio on this one. This was not a vital project. Just a wierd fan commentary I didn't want to watch on my computer.
