TV not starting (renewal of handle)

[wpialum]

I have not been able to get Live TV to start. I choose a channel, the AC3 filter icon shows up in the system tray, but I get a black screen with no audio. My NPVR log shows a repeating "Client about to request renewal of handle: 150003", and the recording length is always 0kb.

Attached are logs. Running Win 7 x64 with all current patches (AFAIK).

Thanks for any help

It looks like the device is failing to lock onto a signal, so never delivers any data to the application.

Does it happen on every channel?

Do you still get channels found when you scan?

argh. That's it. Thanks for your help. I think one of my tuners is going bad. I started from scratch and scanned with both tuners. One found 3 channels, the other found 30 or so.
