HELP!!! DSP 4.0 project won't play when burned (no issues with other projects, though)

Everytime I burn a DVD from a project i have in DSP, it plays on all but ONE DVD player that i have two duplicates of (so i know its not a developing issue with my DVD player). I've burned a number of other projects just to test if this player has issues recognizing DVDs burned from my system (1.8 Ghz G5), but its just the ONE project.

I came to the conclusion that one of my project assets was corrupt. After a number of tests, I mastered all of the MOVs that i used to encode mpegs from to DVCAM tape.....re-digitized them, re-encoded mpegs and then rebuilt the project from scratch on a completely different computer (Macbook Pro w/ same DSP license). Still having the same issue though.

The only successful burns i've had were when i deleted a track from the project. I thought that the assets contained in that track were definitely the corrupt ones, but deleted another track and replaced the original one i took out, and it burned and played again. I'm positive that this wasn't due to decreasing the file size of the DVD, b/c i've also encoded the files to bring my project size as low as 3.6 GB, and it wouldn't play when burned.

My gratitude goes to anyone who might be able to help. The DVD will be widely distributed, so it not playing on my typically reliable player concerns me. Thanks all!
