A couple months ago I started having problems with my TV1 remote when selecting shows on the DVR. It used to be fast but now when I select a show to start there is a slight pause and then the program starts. Or if I delete a program there is a pause until the deletion begins. I even replaced the batteries too. Is it the remote control or is it the hard drive being slow from having so many shows recorded then erased. Too bad there wasn't a way to defrag it. I have the 722.
