I've got an AMD system with ATI USB hardware.  My HD-PVR went from
reasonably reliable to very flakey when I upgraded from 32-bit Fedora 12
to 64-bit Fedora 14.  It now locks after about half a dozen recordings,
but I can't trigger the problem outside MythTV.  It looks like some
combination of MythTV, OS, and hardware is required to trigger the
problem.
