I have had a R-15 dvr for about 6 months. About a month and a half ago. I noticed that programs I tape lock up the system or drop out. And I have to hit the reset button to fix. I called a tech and said I should have the software fix. But, says I need to do a complete reboot to fix the problem. I held off since we have a bunch of shows taped that are fine that we wanted to watch. But, its getting worse. I always assumed if you hit the reset button it would wipe the drive and reboot. But, all it does is reboot. How do you reboot the system from scratch (erasing all saved programs)?? Also, is anyone else having this problem with the R-15?
