I'm new to this forum, so please excuse me if this question has already been asked. I have a Scientific Atlanta Explorer 8420HDC DVR through Time Warner that has been acting up. It appears that I'm going to have to swap it out for a new unit. I have lprograms recorded (for my Wife) that I would like to save. Is it possible to copy these to an external hard drive through the eSATA port, than transfer them to the new unit? Thanks
