I'm running Mythbuntu 9.1 (Karmic) and had flashed my HDHR to firmware
20091111beta1 from firmware that was from around 20090414...  it went ugly
with stuttering HD video and audio...  I backed the firmware to 20091025
(or whatever October firmware date they publish) and the HDHR is fine.

You didn't mention firmware, but it's a consideration.
