Folks: This might have been discussed before, I am just wondering why the HD picture from my HR20 can't seem to keep up? I was watching one of the Transformers movies and I saw some artifacts, stuttering, and pixelation on fast or busy scenes. I tried changing the format from 720p to 1080i but it did not seem to make any difference. I have a 120 Hz TV. I know D* only transmits at 60 Hz for most of its channels. Personally, I prefer watching a movie from a Blu Ray. What gives?
