Ahhh, that must have been what I saw yesterday.
On a semi-related issue, I had the World Cup Encore on (on 140 or 144, can't remember) and I got the signal-loss screen and it flipped to the SD feed on it's own. After quite a while (I wasn't sitting down watching - I was doing other things around the house), I noticed it's still on the SD feed. I thought it should have cleared up by now and toggled back, but it hadn't. So I hit CH-UP and the next channel was in HD, then CH-DOWN back to the channel I was watching and it was also in HD (now).
Was the timing just a fluke ? Doesn't the receiver (shouldn't say just the Hopper as I seem to recall my 722k did it as well) 'check' the feed and change back ? How often ?
