My assumption was that the recorded shows would be tied to the access card, not the specific unit. I also assumed if they gave me a replacement unit that I would just move the access card to the new unit.
Can anyone say whether that's true or not?
On a less positive note, the Seagate Freeagent 750GB I purchase at Costco doesn't want to work with my HR20-700. I cabled them together with an eSATA cable, powered up the Seagate, gave it time to come ready, then plugged the power cord back into the HR20. Each time it comes up with the internal drive. :-/
