Re: Mac: extracing VIDEO_TS audio; replacing VIDEO_TS audio?

So I did a new mux. I used mpeg streamclip to demux a M2V. I then used ffmegx, tools, mux, selected the m2v in the video field, the fixed wav in the audio field. I selected "author as dvd", mux as dvd Sync 0.

The footage seems fine. The file size went from 3.09gb (original) to 2.58gb (new)

Mac DVD Bitrate Paranoia states the origional was 9.32mbps the new one is 7.96mbps

I also lost 10 chapter marks.

I would REALLY love to figure out how to do this with absolutely no loss in image quality. What do you think?

Here is the info... See anything odd?
