Using one of the above to receive the HD broadcasts using gbpvr. While it works most of the time, occasionally Windows will "lose" the device. This manifests itself in the following manner

1. gbpvr records a file with no bytes, and then tries to record the file again with a suffix of "-1" - sometimes that will work
2. gbpvr tries a couple of times, shows it's recording but no bytes are getting written
3. The device yellow light is on

I have tried unplugging the device and back in again, resetting the recording service but nothing really works apart from re-booting the PC. Even that has failed once.

I am wondering if I have a faulty unit or there is something inherently unstable in a USB tuner?

Just wondering how others are faring with similar devices
