fwiw, digital audio coming off my Motorola QIP-6200 into my hdpvr was pretty thoroughly hosed (had a really tinny quality about it, painful on the ears) until a firmware update about 6 months ago. Audio off a DVD player was just fine. So yeah, there's definitely some device-dependent issues that have to be dealt with on the hdpvr side.
