Just noticed a problem.  I put it on the Sugar bowl last night (over the air)and after watching for a minute, I got some small black bars in the top left with writing in them.  When I switch to a regular sat. channel it is still there.  Unplug the 811 and it goes away till I watch over the air programming again.  Then it is back, if I leave it on the channel it goes away then comes back.  Any ideas what this might be?
