Because I'm bored give me an hour and I'll check out my old 625 that has been deactivated for at least four years. (if it works)
Update: Well the old 625 Dishplayer still works. It's only been deactivated for a little over two years but my recordings still are playable. You shouldn't need to have it connected to the DISH, nor would I connect it to a phone wire because it might "call home" but anyways once you power it on just press the DVR button twice and the recording list will come up. Play the file and it should play. My 625 Player is operating on software L548JYD-N. If you do have it connected to the DISH I think you get the monthly freeview channels.
It might also be worth noting that this receiver was removed from my account because I upgraded to a 2 hopper 3 joey installation from a VIP722, and the 625 in question, not because of a failure to pay, etc.
