Thanks to you guys, and a bit of time fooling around, I seem to have the "big picture" of how this works now, and I'm pretty happy with it.
But now I need to take a big step backwards and ask an amazingly basic question:
How do I STOP a recorded show that I'm watching? As there is no stop button, pause seems to be the only option. But then what? Normally when I stop a show it is because I'm done watching it for whatever reason (I padded the end, and didn't need to watch all the way to the end, etc). On my Dish box, I'd press stop, and it would ask me what I wanted to do next - including delete. On the TiVO How do I stop the show I'm watching, and most quickly get to a menu where I can delete the recording and start watching another? right now I'm using pause, then the TiVo button, and drilling down into "my shows." There must be a more direct way.
