Does the iDVD audio HAVE to be PCM?

[KeepItSimple]

Is there a way to get Dolby Digital audio when I use iDVD instead of PCM?
I like the menus a lot better than the Toast ones however Toast can make it a Dolby Digital or PCM DVD. I don't see that option in iDVD 6. What am I missing this time?

ALSO, is there a way to make 2 or more programs brought into iDVD to play continuously without going back to the main menu in between? I just want to have everything play before it goes back to the menu but I can't get it to do that. Once again Toast has that option but I don't see it for iDVD. I wouldn't even bother with iDVD and stick to Toast except for those cool menus. Damn you iDVD!!!
Any ideas?
Thanks!!!

iDVD can't do either. You would need DVDSP for that.

You can use QT Pro to combine the 2 movies into a single reference file, and drop that into iDVD.

An alternative is CaptyDVD 2 which is available at pixela-1.com. It has motion menus but also does AC-3 audio, including the ability to use existing muxed MPEG videos. It also is bundled with LaCie's FastCoder at lacie.com that is being closed out for about the price of CaptyDVD 2.
