I know it needs a signal from the dish. And I know the guide data will not be there. But can a 722K or 722 still receive and record OTA after the subscription is ended?
Fooey. For $50 you can get an ATSC tuner card and record to your hearts's content. No DRM either. (I don't know this, but I suspect the DTVPal DVR doesn't make it easy to get at your recordings.)
