Why is it that an iMovie slideshow looks/sounds great when played back on my computer, but looks like c**p when played back on a disc authored with iDVD (both on the computer and HD tv)? The resolution is terrible and even the sound is worse. Given that the file size goes from 800MB in a QT.mov to around 300MB in the .proj and .img files, I guess I shouldn't be surprised. What's the alternative? I'll be getting FCPX-- If I recreate projects with that, and burn it as 720p or as BD, will I be assured of seeing the original high quality? Also, if I streamed my current QT.mov projects through an ATV, would the quality be preserved? I just want to be able to share these things and not have them look like garbage, when they didn't start out that way. Thanks!
