You can use EHDs with DirecTV as well. If you're concerned about your current recordings, then watch them or archive to DVD or your PC before you switch. My main concern about switching to DirecTV would be the loss of 30 HD nationals. You'll also pay more for your 3 room setup (I assume) with D* ($7 for room 3 versus $6 for room 2 + $6 for room 3 + the cost of receiver 3). MRV is another $3.
