I found out the hard way today that I received a DirecTivo on Ebay that was in collections. I even checked with Direct before purchase, but the seller sent me a different receiver (different receiver ID) from the one he advertised. The unit was a Philips DSR708. Unfortunately, I spent the time and money to upgrade the unit with a new 250MB hard drive before I saw today that the receiver ID's were different. I have another Philips DSR708. Is it possible to just swap out the hard drive from one to the other being that they are both the same units? I'm pretty sure I used the image from a 3rd DSR708 that is currently active on my account to create the new drive, so I would think that it would be a simple swap.
