[mythtv-users] Torn HD video with MythTV under Gentoo

My setup involves a 3Ghz Dell Optiplex GX/270, with a 350G SATA hard drive,
1.5G of RAM, and a firewire connection to a Motorola DHC-3200 STB. I was
using a Ubuntu-based setup, which worked mostly, except that it would act like
my box was just a bit too slow to keep up with playing almost-full HD video
(I have the STB set to 1080i, but my monitor is 1680x1050). A lot of time,
the video on an HD channel would be "jerky", or the audio would stutter, or
I would have other problems.
So, I decided to try to re-do everything with a Gentoo-based setup. Under
Gentoo, it does feel a lot more responsive. All the SD channels work fine,
no problems. Some of the HD channels work, like the HD version of the
History channel. But a lot of the HD channels have "torn" video; the video
has severe horizontal tearing, like adjacent scanlines are offset or something.
I can't quite describe it.
Anyway, I was wondering if someone who has a working Gentoo-based setup
could give me your make.conf file. Perhaps I could use that to do my setup
again and figure out where I went wrong.
I hope I can figure this out, because under Gentoo the few channels that do work,
work beautifully. All the problems I was having with Ubuntu have gone away with
Gentoo. I just don't know why I'm getting that tearing problem with most of the other
