Plays in sssslllloooowwww motion

I have a strange problem. When I play DVDs sometimes it plays in slow motion.
Like, really slow. 12fps. The sound is played in slow motion too, like you're
playing a 72rpm record at 30rpm. Actually even slower.

It doesn't happen all the time, it seems to happen when I go straight to a
scene using scene selection but not if I play the movie right away. Once it
starts it happens everywhere, even the main menus or if I go to play. And if I
go directly to play then it doesn't happen even if I go back to the root menu
and jump to other scenes using the same menu that triggers the problem if I
use it to start with.

It sort of seems to me like a variable isn't being initialized and the sound
card sample rate isn't always being set properly when the framerate of the DVD
changes. So sometimes it's in 24khz when it ought to be in 48khz. I think I
see the same problem in reverse too, the menus seem awfully fast, 60fps. But
the audio sounds sort of reasonable, though it's hard to tell because it's
just a menu.

This is on a new P4P800 motherboard with an intel i810 audio using the OSS
drivers from linux 2.6.1. Sound seems to work fine in xmms and other apps. And
the fact that it works fine in ogle sometimes makes me think it's ogle failing
to do something consistently rather than a hardware issue.

I don't get any messages about trying to get 44khz and getting 40khz or
anything like that.

This is what it looks like when the problem occurs (the 30fps is the menus as
i navigate to scene selection, the 12 fps is when i jump to a scene):

This is what it looks like when I just go to play directly and things work:

The 24fps is when the movie is playing, the 60fps is the menus as I navigate
to scene selection but it goes back to 24fps when I choose a scene.
