Upon looking over the list archives I see that I misremembered the
facts. What was added last year was support for variable-bitrate
recordings (which helps to ease the playback burden), and I think this
was done on the MythTV side, not on the firmware side (Or was it both?)
In any case, VDPAU has of course completely and utterly made all
HD-PVR playback concerns obsolete. John Nissley, the original poster,
is running trunk so he has access to VDPAU support, and if needed a
VDPAU card costs $30.
Sorry about that. Guess I should have checked the obvious first. I have an AMD 5600+ which I thought would be enough CPU to handle the playback burden but I guess it is not.When I check TOP during playback I see that one of the CPU's is at 100%. I guess it is time to see if VPDAU works on my NVIDIA 8200 motherboard.Thanks again for pointing out the error of my ways.
