I started looking into the problem and yes, the problem occurs when
tuning fails. In the case I traced down, TVRec::TuningSignalCheck()
calls scanner->StopActiveScan() and it never starts again. It may be
possible to replicate by simply disconnecting the antenna at some point
after EIT scanning has started.
I will apply the patch tonight and start testing to see if it works, and
may try disconnecting the antenna to try to replicate the problem before
and after the patch.
