Unsubbed S2 DTivos work fine as a remote dummy terminal. I have mine connected to a sat feed to eliminate the nag message when there's no sat signal. The only other nag screen you get is when you go to access the Now Playing list and it tells you to activate the DVR service. Press Select and you can navigate through the menus and watch your shows with no further nags.
Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!
