Tunning a ATI TV Wonder 650

[DRB]

When I had TWC I used the ATI TV Wonder for tunning SD, it was a cheap back-up for recording more steams. Now that I have moved to Directv I am looking for other cheap ways for recording. I can pass the D-TV signal tru the ATI 650 via s-video to Sage but can not control the tunning. I would idealy like to use the DirecTV HTTP channel changing but that is not an option I can choose in Sage with the 650. Is there a way to do this?

I currently have [1] HD-PVR USB running on WHS and may buy another, or I may rebuild the server and buy a couple of the Colossus cards.

I like D-TV better than cable but cable provided a much cheaper way to record many steams. What is the best/cheapest way to record D-TV making the best use out of box rentals. Would a HD-DVR provide me with 2 steams that I could tune? One via the DirecTV HTTP channel changing and the other with DTV2PC? What are some tunners that could be used with SD D-tv.

Thanks for any help
