I have an issue that has plagued my HR20, and that is the native on/off. I have a tv that does not support 720p (mitsubishi 42" rear projection 1080i set). When I select the resolution (480i, 480p & 1080i) and have native on the SD channels are distorted, wavy like. However when I onyl select 1080i and keep native on, the SD channels are fine. Also if I change native off and keep the resolutions checked as noted above it works. There is something I am not doing right to not get it to work. My tv is set to "standard" for format and the box is set to pillar box. Any help that can be given would be greatly appreciated. I am at work right now, so when I get home I will play around again.
