How do I delete a program that is scheduel every day at the same time and channel if I no longer have the original remote that had a clear button. The remote that I am using has a clear button but it doesn't work to delete the program. I have tried unplugging the VCR for an extended period of time. When I plug it back in it looks like the program is gone, until I run the setup of the VCR and then it is back.
