Hi,
I've had 2 Nova-T usb sticks installed and working perfectly for about a year, however it took some time to figure out why they weren't working. The way I approached the problem was to use a utility called ScanChannelsBDA_UK.exe (Google for it).
Firstly number the sticks.
Then insert them and check that BOTH are detected. If they aren't, remove one (doesn't matter which one) and reboot the computer. Then run ScanChannelsBDA_UK again and check that one's detected and do a quick channel scan to check it works. Remove the first stick and insert the second stick and reboot. Check that it's detected and do a quick channel scan. This checks that they both work seperately. The problem I had was that they were both detected but only one worked and the device which worked would change in ScanChannelsBDA_UK.( you can tell if this happens - that's why you number them!) I came to the conclusion that because each stick needs about 500mA, two of them on one hub causes problems for some motherboards (even though each usb port is supposed to provide 500 mA). It didn't seem plausible to me that the onboard USB hub chip with 4/6/8 ports could provide 2/3/4 Amps without going into thermal overload and shutting down some of the ports - this proved to be the case with my AsRock ION. I bought an external self powered hub and all the problems with ScanChannelsBDA_UK disappeared - both sticks were detected and scanned perfectly. I assume that the reason that the one which worked seemed to change depended on which port shut down first. If Hauppauges own software detects them both but only one works, then this might also indicate a USB power fault. If they don't work perfectly with
ScanChannelsBDA_UK then they won't work with anything else. You could try connecting them on different hubs if your motherboard has more than one.All that messing about rebooting the computer is so that the device drivers get loaded cleanly while you're doing the testing.
The next problem was to get GBPVR to detect them. As mentioned it's important to get the instances right in BDA.ini, here's the part of mine that concerns the Nova-T's :-
[Hauppauge Nova-T-Stick type3(1)]
TUNING_TYPE=DVB-T
FILTER_TUNER="WinTV Nova-T Stick DVB-T Tuner (Dev1 Path0) "
FILTER_CAPTURE="WinTV Nova-T Stick DVB-T Capture (Dev1 Path0) "
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport
[Hauppauge Nova-T-Stick type3(2)]
TUNING_TYPE=DVB-T
FILTER_TUNER="WinTV Nova-T Stick DVB-T Tuner (Dev2 Path0) "
FILTER_CAPTURE="WinTV Nova-T Stick DVB-T Capture (Dev2 Path0) "
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport
After you've edited BDA.ini you can then select them in the device configuration screen of GBPVR Config.
Hope this helps.
Jim.
