In my HTPC I substituted the Compro VideoMate S350 with the TBS 8921 to be able to continue to watch BBC HD (after their switch to DVB-S2). After installing the card + drivers (downloaded from TBS website, the correct ones - all looks good in Device Manager with two entries in the video section and one in the HMI section) I went through the "Setup TV Signal" procedure in WMC (Windows 7 32bit) and I received the first surprise: I was suggested to use Hotbird 6, 7A, 8 and was shown a strong signal for this satellite when my dish is aimed at Astra 2D. I changed manually to Astra 2D and although it showed no signal strength, I finished the WMC setup process. WMC seemed to pick up a few satellite channels (the total moved from 85 with the DVB-T tuner only to 105 after adding the TBS8921) but way less than expected (the Compro VideoMate S350 picked up hundreds with the same signal), and anyway when I tried to watch one of the few channels it picked up I got the message "No TV Signal".
I also tried to use the TBS8921 with the included TBSviewer, but when I went to Options... Hardware there was no card in the hardware list. At least WMC found the card!...
Anything suggestions or should I just return the card? Thanks!
