I too have experienced some frustration with this... I have Nero and SoThink DVD creation software as well... SoThink has a nifty chickbox that allows you to extend the menu soundclip for the length of the soundclip. (So the DVD menu sound plays all the way through before repeating, rather than cutting off in the middle).
So I know this is POSSIBLE to do. What I don't know is whether it's possible to do with Windows DVD Maker. Each of these programs has their strengths and weaknesses. Windows DVD Maker puts together a nice DVD Menu, with professional looking menus (complete with scene menus) already put together. The other two that I have (Nero and SoThink) don't that I'm aware of, so for my next couple of projects, I'm going to use Windows DVD Maker regardless...
It would be nice though, if I could make a DVD Menu with Windows DVD Maker, that didn't cut my custom sound files off in the middle... even if they run 45 or 60 seconds or longer. Is there a fix somewhere out there for this? Some obscure tweak that would allow me to extend the play time of the menu sound for a video DVD menu?
Thanks in advance if anybody knows, and if I find one or figure one out, I'll post it.
