ATSC Tuner Sometimes Works, Sometimes Not

[bendrl]

I have a Hauppauge HVR 950Q that I bought to use with GBPVR. I installed the driver and the WinTV product that came with it. WinTV works well -- even the analog portion which I'm not really interested in. No problems with watching or scanning channels, etc.

I set up GBPVR to use the 950Q using with this BDA.ini:

[Hauppauge HVR-950Q]
TUNING_TYPE=ATSC
FILTER_TUNER=WinTV HVR-950 BDA Tuner
FILTER_CAPTURE=WinTV HVR-950 BDA Capture
PIN_TUNER_IN=Input0
PIN_TUNER_OUT=MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport

GBPVR recognized my 950Q, and during the channel scanning, it found the expected 15 or so ATSC stations.

The 950Q device has a LED which lights up when it connects to a station. During the scan, the LED lit up when it finds the stations.

However, once I started using the system via live TV, about 80% of the time, GBPVR will report that signal strength is 0 so that no video appears (the LED is off). About 20% of the time, the LED on the 950Q will light up and live TV starts. I definitely know the strength of the signal for the 15 or so stations is high.

Any ideas? Thank you!

Thanks for your reply. Yes, I have that set to 'true.' Before I installed my 950Q, I uninstalled GBPVR & reinstalled it. It was set to 'true' as a default.

I'm not really sure.

Reproduce the problem and post the logs and I'll take a look.

OK. Here they are. I started live TV and got the signal problem a few times. I then restart GBPVR and started live TV and it was fine. Sometimes restarting will fix it. Sometimes not. THANK YOU!

Sorry, I dont know - I cant see any errors occuring in the logs. It just looks like the device fails to lock onto a signal.

I just had something like this start out of nowhere. I tried the very analytical and scientific fix of tossing the card into a different PCI slot. Worked.

I have a 950Q, but using it with QAM, i dont have the no signal problem, but when i was originally setting it up i found that one of my USB ports were more tempramental that others, I would make sure that there isnt a loose connection, to either the antenna or usb port, and i would start with a USB port on the mainboard first for trouble shooting, or a powered USB hub.
