I have a HR20-700 and 1080P Samsung DLP TV (HL-T6187S) connected via Component video. I use the TVs HDMI ports for Blu-ray, Xbox, etc. The DVR is set to native off and 1080i. Basically, I am pleased with the picture quality plus channel surfing is much faster than native on. I was reviewing some prior posts on "native" and someone said that if you have a 1080P TV then you should set your DVR to off and select both 720p and 1080i. I'm confused as I thought if you selected native off then you could only select one resolution.
