Many of us here on the forum have the card. From what I can tell, I am having more software problems than most, but I remain very pleased with the card overall. I have had to accept the fact that this card is still somewhat in beta shape and will have problems that Telemann is still working out.
With the latest beta 2.2 drivers, the system can be used as an HDTV tuner with very few issues. Recording and playback also are working well, but there are still a few bugs being worked out. See my post and others in the Home Theater PC section of this forum. The card's second manufacturing run is still being held up due to parts shortages (RF can, for example), so don't expect availability until April.
Your other option is the Hauppauge WINTV-HD card, which is supposed to have recording functionality within 2-4 weeks, and is shipping now.
