Summary: Super little satellite TV card. I'm using mine with Windows 7 64bit drivers from the Compro website.
I do not use the DTV4 software, but am using Windows Media Center, which is doing a very good job. BBC HD is received and recorded very well.
I also use the built in Media server with Windows 7 (Media Player 12) to stream any recorded material (HD also) to my PS3 and watch what I have recorded on my TV.
Conclusion: This card is great stuff. The software that comes with it is a bit poor, but if you use Windows Media Centre to scan for channels...it''s a great card! At the price, you really can''t complain! Freesat on your PC for Â£23.99...I''ll have some of that!!!
Conclusion: This a fantastic Product for the asking price, can pick up all the current satellite channels including BBC HD. Recommended to be used on Windows 7's Media Center with a H.264 Codec for the HD Channels :-)
