I don't think that's what the problem is...
I have a very fast development machine (E5 3.2GHz, 8GB RAM, all
database on SSD, recordings on external RAID5 array).
I've noticed the exact same thing now when I enable VDPAU with the
deinterlacers active using the nouveau drivers.

playback stutters. I'm for once entirely sure it's not a machine speed issue
It doesn't occur with nvidia drivers. and mplayer plays that exact
same file with the exact same deinterlacers just fine.

there's something else at play, and his testings are very interesting
indeed... I think he's definitely on to something, something myth
doesn't do properly and it just happens that under some circumstances
it becomes a problem
