live tv stops after a few seconds

[michaelrmgreen]

When I select 'watch' I get a few seconds, typically 5 but sometimes only 1 or 2, of prefect picture and sound. The picture stops and sometimes I get a no signal error message. The picture is prefect on my regular Freeview TV.

Any ideas? TIA

SOLVED

I installed the PVR application that came with the tuner cards (Leadtek DTV1000T). I then uninstalled GB-PVR and reistalled a fresh copy. I had only installed the driver previously.

Oddly the signal strength is now shown as -3000, quality 99 now. Very odd.
