 I have a "Video over DSL" box here which I hook up to the composite input
 of my capture card. When I try to change channels to the channel defined
 for my composite input, it switches inputs:
 2005-08-30 21:54:09.609 Channel(/dev/video0)::SwitchToInput(in 5)

 And next it tries to tune to a channel. I have left the frequency id blank
 for this channel since there is no tuning going on, on my composite input.
 So this is what happens:
 2005-08-30 21:54:10.125 Channel::GetCurrentChannelNum(): Failed to find
 Channel ''
 2005-08-30 21:54:10.133 Channel(/dev/video0)::TuneTo():
 curList[-1].freq(-1)
 2005-08-30 21:54:10.147 Channel(/dev/video0)::TuneTo(): Error, failed to
 find channel.
 2005-08-30 21:54:10.156 SetChannelByString() failed

 And next it switches back to the previous channel I was watching. Whole
 backend log attached.

 I'm attaching a patch that skips tuning for channels which freqid is
 blank/null.
