hello.
just needed a quick answer about two things.
compressing a 23.98 timeline and/or a 29.97 (24p) timeline to DVD studio pro: Mpeg 2 or mpeg 4. I see that mpeg 4 has a label for 24p, not knowing which it reffers to and understanding that mpeg4 is a crappier compression rate.

also
letterboxing. is it possible for a 16:9 image to be letterboxed on a 4:3 tv and 16:9 on a high definition tv like the store bought DVDs? that might be a lil bit of a process, so if you could either describe the steps from FCP to DVD or find a link other than an apple.com site cuz apple hasn't been very fun for figuring this out.

thanks

i can help with the first part:

I always export as mpg2 and use the standard frame rate which i believe is 29

It should say 29.97 fps. You will be able to produce both the 4:3 and 16:9 if you use a type 18 DVD or DL -R or DL +R, however I am assuming you are on a G5 so -R. They basicly place two versions of the film on the disc, but you need that extra space to accomodate both versions. There currently is no way to flip on an option and have it do both. You just need to render two versions for disc.
