Hi
I just experienced the same problem .
Finished sequence on FCP, captured from DV, and edited with DV Sequence setting. Everything looked fine on timeline playback.
Then i exported sequence as a .mov file, turned out about 2.7Gb file. Popped it into Titanium Toaster and burned it as DVD.
DVD looked fine on cmpt playback, but stutters on external DVD player.
Anyone got any suggestions?
