I had an interesting problem with my R15-100 unit last night. I was watching TV and the R15 turned on the red light indicating that a rerun of CSI was recording. All was well, except that I lost the picture of the program that I was watching and was not able to get a picture on any channels with the exception of my local channels (that are through the satellite). All other channels were just blank black screens. I went in and cancelled the recording and was then able tune to all channels again without any issues. Any ideas on why this might have happened? Has anyone else experienced this?
