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.
