I just don't know if I can handle Native Mode and the delay. I flip a lot. In one other thread I read there was a guy who said to keep everything on 720p because a progressive signal is better than an interlaced one. The TV will upconvert the 720p to 1080p without interlacing it. I don't know what having 480i and 480p selected will do because I don't even think my TV supports those low resolutions. If I recall it's just 720-1080p, but I could be wrong.
You're getting confused between the resolution a broadcaster may use for a program, versus the resolution the receiver can send to your television.
Example: You are watching a football game on ESPNHD. That is broadcast in 720p, which seems to be the best for fast-motion signals. Your HR-20 receives the signal as 720p, then can either output it as a native resolution (720p) or output it to the resolution you select, such as 1080i or 720p. Either way, your set will then convert it to 1080p. If you set your receiver to output in 1080i, the signal is going from 720p to 1080i to 1080p.
-or-
You are watching a movie on HBOHD. That is broadcast in 1080i. Your HR-20 receives the signal as 1080i, then can either output it as a native resolution (1080i) or output it to the resolution you select, such as 1080i or 720p. Either way, your set will then convert it to 1080p. If you set the receiver to output in 1080i, the signal is going from 1080i to 1080p.
Notice in the second example that there is one less conversion in the video signal. That is because the receiver is outputting the 1080i signal as the same resolution it is being broadcast in: the native resolution. Since this set is a 1080p set, and since the HR-20 can not output in 1080p, it would be best to turn native resolution on, thus reducing the number of conversions the video signal is subjected to. However, if you have a 720p set, it is best to turn the native reolution off and set the HR-20 to output in just 720p. That way there is less conversion.
Remember, no matter how good the video scaler is, the more a signal is converted up or down, the greater the chance of video errors.
