I don't have the time, or patience, to search this entire forum to see if our problem has already been discussed. If someone knows that it has, feel free to point me in the right direction. We have an R15-100. My husband set it to record several shows on Wednesday late afternoons while he is working. When he went to watch them, he found nothing - and the machine was set to record the same shows, at the same times one week later. We reset the machine, and reprogrammed for today's episodes. I went to check a bit ago and nothing was being recorded. Once again, the machine had moved the recording info one week ahead - to 2/6. Has anyone had this or a similar experience? Is there a solution?
