When did "Record rest of episode" after pausing or rewinding stop working on the 722k ? In the past, you could rewind a show, hit the "Record" button, and it would start recording from that point until the end of the show (or whatever option you chose).
If you attempt this now, it will start recording at the current time, i.e. current time is 10:10pm, you've paused a show from 9:30-10:00 at around 9:45pm, you'll end up with a recording of the show that's on at 10pm until it's normal end time.
