Another Microsoft limitation -- without UDF, it cannot handle LARGE files at all (> 2GB, I think). Which is why DVD-Video discs always have the main feature split up into a bunch of small VOBs.

EDIT: the video files I'm dealing with here, began life as 40GB recordings (6hrs each of HDTV at 1080i), and have been squished down to 720x400 resolution, resulting in 3.something GB files.

Again, Linux doesn't care.
