My entire project is comprised of animation produced in Poser and some stills.  I think I'll ignore fields for now.  Thanks so much for taking time to respond to my questions!

Thanks for this info.  What I think I'm hearing is that I don't need to work with fields for my particular project if the end result is to make a high quality dvd that will play on tv's, but won't be broadcast on tv's.......

If it doesn't take too much typing, can you please tell me a little about fields -- how and why to work in them?  I've seen the settings but have no idea what to do with it.

First of all, thank you so much for replying.  One line you wrote unlocked the puzzle for me.  You mentioned loading uncompressed into Roxio.  I had tried loading uncompressed into Roxio, but the Roxio preview couldn't play it back smoothly so I assumed it wasn't working.  After I read your note, I went ahead and burned a dvd anyway and it worked nicely.  So, it's not always a matter of what you see is what you get!

And I just wanted to mention that I use AfterEffects to crop and brighten (when needed) scenes from Poser, and then I put them into Premiere to build my movie using layers of audio and transitions between video segments, etc.  I don't know AfterEffects well enough to be able to build it all there.  I should do some of the tutorials to learn more about it.
