sorry - I wasn't clear. I meant "native resolution" to mean "native resolution of what you're watching." That's why I went further about what you tend to watch most...
I personally put up with the flashing because i like the idea of watching the channels the way the networks broadcast it. I have both of my HD TVs on Native. I have both a 1080p & a 720p flatscreen TV. If my old Samsung CRT HD TV had not of died,then I'd have it set to 1080i on my HD Receiver.
