I just blew away my myth backend, and re-installed with Ubuntu Feisty
+ the Myth packages from the distro.   It was a completely clean
install, reformatted the OS disk, new MySQL DB, etc.

I ran into my share of dbus & hald problems, but Myth worked fine.
Channel scan, recording and playback are okay..

This is on Feisty x86-64, Athlon64, kernel 2.6.20-15.  pchdtv HD3000
and DVico FusionHDTV3.  QAM cable source,  high channel scan, it
picked up my handful of clear local QAM256 channels.
