Update, in WMC the card isn't completely working right, even though it works in WinTV fine. DVB-S2 won't work in WMC, even though it should, and some other channels are wonky. Scanning 95w, it picks up all the CCTV channels but will not play the CCTV Doc one and list the others wrong, but those will play. Some channels from 97w would scan in but not play on the computer or extenders until I did a update for WMC called X Box Optional Media Update, which was a PITA, it's not received within normal updates and I had to do it through X Box Live on one of the X Box extenders. Still a good deal for $31 and I haven't given up on trying to get it all working correctly yet!
One nice thing I found was a program called Guide Tool which allowed me to add EPG within WMC for sat channels like Ebru, etc and also for some ATSC channels that I receive which are out of my zip area and that WMC never had EPG info for, really nice, that. It also makes it real easy to remove channels from the WMC channel line-up, which is very helpful because when you rescan a sat transponder in WMC it will just breeze over any previously detected channels and only looks for new ones. Without the Guide Tool, in order to do a rescan and have it detect anything, the only option is to completely go through setup again, really stupid, that.
Hauppauge has a patch tool for WMC to fix missing sats, channels, DVB-S2, [MCEDVBS2PatchTool.exe], but I haven't been able to get it to work quite right yet.
