Actually I recently discovered my video player (Zoom Player) allows me to
select which DVD navigator I want to use, and sure enough, when I use
Cyberlink's navigator, movies play back correctly at 1x. Maybe Microsoft's
navigator buffers too much data, causing the drive to 'think' its reading a
data disc and not playing back a movie? I dunno... on the other hand, if
there was something inherently wrong with Vista's built-in DVD navigator,
you'd think a *lot* more people would be having problems. Either way, the
problem is more or less fixed for me, though the whole thing is still kind of
baffling.
