It is a known fact that the "Resume" option will not work while the recording is still being done. "Resume" only works after the show has stopped recording. As far as the "...live tv..." and "...rewind..." problems, I don't know. I start a show all the time while it's still recording and the FF and RW works just fine and I don't get the "live TV" message either. It could be a problem if your getting a poor signal.
