I have posted before about having to reboot my HR21 at least once a week. I seem to loose the signal on tuner 2 always and have to reboot to get ant channels to work. I also notice the signal strength is o on SAT 2 when this happens. I also noticed that when I am recording a show like last night I can still watch that show but nothing else shows up. Again it appears tuner 1 was recording the show. Is there a way to switch between tuners like on the older DVR? Are there any new software releases that may address this soon. I have had the dish looked at and it is in good position. I also notice that when I reboot that It gets stuck on the step 1 screen for a while before it goes to step 2 then it stops at 47% for a while before continuing with the download. I would say it can take 15 minutes just to reboot
