Hello everyone. Hope you can clarify a couple of things for me.
1. When I made a stereo AC-3 file and played it in DVDA it sounded really bad. As if someone had turned the treble knob down to zero on a hifi system. It was encoded with the standard setting, quality under 448 as specified in the manual, I think it was 192. The wav-file, 48 000 stereo PCM, I encoded instead sounded perfect. What's up with AC-3?

2. What format should a video file for animated menus in DVDA be? I made'em mpeg 2 DVDA standard but now when I'm preparing the project it has to recompress. Why?

I might have a guess for you for #2 - if you're refering to animated menu buttons and not animated menu backgrounds...

The DVD spec actually does not allow animated menu buttons, so the way animated menu buttons are "faked" is by compositing the animated menu buttons frame-by-frame over the background (still image or animation) to get just an animated background. Pretty tricky, eh? Anyway, this would explain why any video you use in an animated menu button will always have to be recompressed so that the compositing can happen.

I see. Well, I have animated menu backgrounds and I made the buttons animated as well, so then DVDA renders it all again to be able to play it. Interesting. Just to be absolutely sure here - if I had chosen not to use animated menu buttons DVDA would not have to recompress right? (DVDA is working for an hour right now so I can't test it myself) :)

As long as the animated background was DVD compliant, I believe that DVDA would not recompress it, although I haven't tried it myself.
