Looks like there are no more unexpected CAM resets, so the reason for the
"channel not available" must be something else. Maybe the CAM doesn't
decrypt?

You could add some debug output to cDevice::Action() to see whether
the TS packets are getting descrambled. Maybe the TS_SCRAMBLING_TIMEOUT
needs to be increased.
