I use an HD HomeRun (classic?) with a PVR-250, Firewire capture and
Hauppauge HD-PVR recordings.

I thought there might be contention for the bus between the HDD, video

interrupted playback which coincided with ending recordings.  Don't
know if newer motherboards/chipsets are designed to minimize bus
contention issues these days.
