When I upgraded my HTPC I also went with a dual-slot graphics card (8800GTS/G92-512) which means I have no room for my MCE-150 PCI card (for analog)
It appears that the WIN-TV-900 would be a good option for me since it is USB, and includes DVB-T as well as analog. The primary reason for using it would be for getting Prime (analog) but the Digital tuner could also be useful as I've noticed that even with the Nova-T 500 (dual DVB-T) there are times when I get recording/tuner conflicts (normally when I have two programs recording on the same time-slot then I try to add a 3rd recording immediately before or after the other 2).
However, since the 900 uses software mpeg-2 encoding for analog (not a problem processing wise as I'm running a E6700 CPU) I'm not confident Mediaportal will support it.
Can anyone confirm it works?
