DVD specs on looping menus???

Does anyone know if, when a menu with audio loops, can the audio loop and the video loop be different lengths or do they need to be the same. I don't know how the DVD player process menus or if it can multitask the data streams and loop the video and audio at separate times so the two don't have to be multiples of each other.

From what I understand of the DVD specs, there must be a graphic or video present to have audio. This would lead me to believe that you can only have audio less than or equal to the menu length.

Yes. But if that audio is shorter than the video, will it loop before the video finishes playing.

No. The spec does not allow for audio and video to be looped independently. There will be silence until the end of the video.

OK, what if the audio is longer than the loop? Do you get a black screen until the audio track finishes?

The last frame of the video is displayed until the audio track finishes.

Sorry SonicSDB but I´ve got a black screen until the audio track finishes and not last frame video, why?

thanks,erick

Actually, you are correct...a black frame will show for the remaining audio portion.

If the audio and video are the same length (or for that matter, the video is equal to or longer), and the menu isn't looped, the last frame will remain (as SonicSDB mentioned)

I was going to post message about this issue.

I understand that the "standard" does not allow the video to loop independently from the audio (or vice versa)... but how about having DVDA do it on its own?

Because DVDA doesn't "smartly" auto-loop the shortest media I had to open my video in Vegas and loop it myself. Unfortunately this will mean that the video will be re-compressed and will loose quality...

Dear SoFo... do you think you could add this option to the next release?
