1. Yes, the 522 has two tuners. One tuner for TV1, one tuner for TV2. You can put the 522 in single mode (both tuners to both tv's, but both tv's see the same thing). On the front of the 522 there's a mode button (should be the top-left button of the button's on the right). Press it. A screen pops up that say's tv2 is currently is use, etc, etc. Just click ok. Now you can record one show and watch another on TV1. But now your TV2 has to watch the same thing as TV1. If you've got a blank screen only, or the bouncing dish logo on TV2, make sure you have "Shared View" Enabled (you can find that buried in the menu). If you have any trouble, just read your manual, it should be in there.
2. Good luck. Haven't tried it, but I hear you'll have some problems.
