I had assumed that you were 'terrestrial' and this is talking 
'satellite' and I think we're both in the UK, so our mythtv-setups may 
look different from what you see.  But it should still be possible to 
scan a single 'transport' on the affected Video Source, so (if you know 
or can find out which frequency you want) reducing the number of 
channels needing attention.
