I have a relatively new R15-100 (about a month and a half old). I have had the following scenario happen now twice - once about 3 weeks in and again this evening. The box will just reset itself - first time was during MNF and tonites was during a playback of a recorded show (CSI). Once this happens, all of my SL's have listings in the History that go out for 2 weeks (extent of guide data at the time perhaps?), that all show "Not Recorded". When this ocurred last time, I waited a day or so and nothing would record. To fix this, I had to do a reset everything and then reset the SL's. I do not have a lot of them set, but it sure is a pain. Why would it set all of the episodes to not recorded in History? And apparently, once this happens - nothing will be recorded. I have seen responses where folks are resetting thier units on a weekly basis - are you doing that via the red button, or the reset receiver in setup? Do you think a weekly reset will prevent this from ocurring?
