I've been running the output of my FTA receiver into the back panel inputs of my 6100 receiver for convenience but noticed today, after leaving it on the back inputs overnight that when I switched to a regular channel it had to re-authorise before it would come on. It kept flashing something like "your reciever does not have authorization to view this channel". I went and checked my other reciever in the bedroom and it was fine. When I came back out it was working.........you'd think that with it powered up it would retain that info but it didn't. It even had to reload the guide. I'm wondering if I left it on the rear inputs for too long if I'd have to phone in and get it re-hit, any ideas?
