What video card are you using? HDTV is MPEG2 format which a lot of video cards should provide acceleration for, but looking at the specs, if you have a suitable video card, I can't see why you should have problems viewing HDTV. Viewing HDTV and recording 2 shows on the analogue tuners might be a problem though - you may want to consider in the future moving to a PVR-500 or a couple of PVR-150s/250s which offer MPEG2 capture and very little performance overhead on the rest of the system.
