First my set up. I have native off and all the resolution boxes checked on the DVR. Now my strange occurrence. Last night I was flipping through my different resolutions on my HR21 (480i stretch, crop, etc then 480p stretch, crop and so on) while I was on SD and HD channels. About the forth time I was switching through them I went from 480p’s last selection then it of course switches to 720p next and then I had this blue hue on the TV. Peoples faces had this blue hue and also at the bottom where is shows what resolution your on which is normally white lettering was now showing in a orange box, weird. When I switch from 720p to 1080i it went away. I tried to repeat this problem by cycling through them all but it wouldn’t do it again. But around the forth time of trying to repeat it I was on 1080i and I couldn’t get past 1080i. It just kept repeating through the 1080i selections. So I went into setup and my native was turned on. I never turned it on. Some how it turned itself on so I turned it back off and of course was able to cycle through the resolutions again. It sounds like a glitch in the dvr somewhere that caused this blue hue and the native turning itself on. What do you guys think?
