Hi Timothy.

I've just had a problem that sounds similar.  I scanned a couple of horizontal 
polarity transponders with my Nova-S-Plus, all the channels were found ok 
with good strength signals.

When I went to Watch TV I could watch the channels off of one transponder but 
the other transponder would not lock.

Eventually I discovered that, even though I set Horizontal when initially 
scanning, it had saved one of the transponders as Vertical.  So check that 
the polarities are correct.

It might also have something to do with Inversion which had been saved to Yes 
rather than Auto.
