For what it's worth, I solved my problem. At the risk of displaying
my own ignorance/silliness, I'll close this out by explaining.
I downgraded my video drivers to nvidia-drivers-96.43.01. This didn't
help, regardless of the Profile settings.
Then, I found http://www.mythtv.org/docs/mythtv-HOWTO-5.html . Using
the "Enabling real-time scheduling of the display thread" instructions
for PAM, I enabled real-time priority. Then, made sure that real-time
priority was enabled in the Mythfrontend's settings.
Once again, I have a working HD frontend! It still gets prebuffering
pauses after commercial skips, but that's no big deal.
Oh, and a couple of last notes:
- This box is an Athlon 64 3200+ (not a Sempron 2600+).
- I'd adamantly asserted this was working prior to Profiles. I'm
pretty sure I previously had this working using the SUID route, but
somewhere along the way during a recompile/install (around the
introduction of Profiles), that got blown away and real-time priority
Thanks for your suggestions,
