Why do I have to demux a/v and other annoyances...

I have a set of program streams from a previous project I want to make into a DVD. They contain NTSC video and 5.1 audio. If I attempt to load them into DVDA I get only the video, no audio. I can demux them and manually set the audio source. This is LAME as DVDA will load the elementary streams if you do it manually on the media properties tab.

Alos, DVDA refuses to load elementary video streams if they end in M2V. WTF? They actually use the extension of a file to determine if it can be loaded?

All in all this is proving to be a monster PITA as I have a lot of files I need to drop onto this disk and I do not look forward to the click-a-thon that will ensue. There is no rational reason reason why this app can not load a program stream with AC3 audio and video. It is a bug.

Oh, and another thing: I want the ability to force no re encoding at all. I need to do a mixed format project (PAL and NTSC content) and I really don't see a way to do it.

Have you, in your life, ever seen a DVD that has both PAL and NTSC video on it?

To the best of my knowledge, it can't be done on any DVD.

There's only one start media on the DVD as far as I know... how can you make it work under both PAL and NTSC? Menus too have to be PAL or NTSC; which do you use? I don't know if this has been done before, but it seems like the DVD specification itself is unlikely to support this. Maybe you can get it to play on computers but I doubt any commercial player can handle it.

I did it but it's a hack.

I render two flavors of the DVD, one PAL, one NTSC. I then copy the NTSC flavor bits to a thrid folder and then overwrite the ones I want that are to be PAL format from the PAL disk. It works, but it's not spec I'm sure. Since this DVD is inteded for use in a PC I don;t have to worry about dedicated players getting confused.

This is my number one problem as well. A useful program should be flexible with file useage. This is one of the issues I look at when editing and authoring. Sometimes it takes several different programs just to do a simple job. VOB files and MPEG2 with multiplexed AC3 audio are very common and valid files that can't be directly used properly with Vegas or DVDA.
