Everything I've seen on forums has told me that you can't move or copy your recorded programs to an external eSATA drive. It'll ruin one of the drives or blow up the receiver. But I found a company on line that says they do that, and also transfer your Prioritizer & To Do list. Of course, you have to send them your HD-DVR and they expect you to buy your external HD from them. I had already bought it & anyway who can go w/o TV for a week? You'd get all weaned from it & then you'd have spent those thousands of $$ for your HD screen/receiver/service for nothing. I have a DirecTV HD-DVR HR-20. I'd like to put the external drive on tomorrow, sort of between seasons. Does anyone know how to transfer the old programs (and programming) onto the new drive?
