I multitask my accessDTV with DVD software, and don't experience any dropouts at all except when the ADTV begins and finishes the recording I get a few seconds of stuttering. This is on a P3 850, so I would think your 800 should be OK.
What version of PowerDVD are you using? TheaterTek may improve matters since it uses the Radeon's hardware support, and should therefore use less CPU.
Are you using software audio decoding, or outputting SPDIF? Same question goes for the HiPix. If one or the other program is doing software decoding of audio that could account for the problems.
