Since I've got the card I'll try to answer a few of the questions that have been posted.
You should be able to use this card with Linux or *BSD as it's based on the BT848 chipset. I have yet to try this but plan to.
I don't know if the tuner on the card supports stereo, but it's worth noting that audio capture is done through your soundcard, not the PCTV card. So if, like me, you're using an external tuner for audio and video (DirecTV box, VCR) that supplies stereo audio, and you patch it to your soundcard's input and one of the PCTV card's video inputs (S-Video for best quality), you will have stereo audio. I have no need for the tuner in the PCTV card.
