The analog side of this device wont work in GB-PVR due to the lack of hardware MPEG2 encoder.
The digital side will probably work, but you'll most likely need to add a section to the bda.ini file. If you run filtercheck.exe in the GB-PVR directory, then zip and attach the filtercheck.log, I'll tell you what that section is.
The analog side wont work with GB-PVR. You should be able to get the digital side working by adding this to the bda.ini file:
[TM6000]
TUNING_TYPE=ATSC
FILTER_TUNER=TM6000 Digital TV
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
FILTER_CAPTURE=TM6000 TV - Digital Capture
PIN_CAPTURE_IN=Input0
PIN_CAPTURE_OUT=Output1
