My mother lives in Terre Haute, IN, and has an HR-23 with AM-21 attached. The DVR was horribly sluggish with the AM-21, but it was her only option... until this week. Now that DirecTV offers Terre Haute locals, I unhooked her AM-21, and reprogrammed her DVR to record shows only from the satellite rather than the tuner. I then reset the receiver. I noticed that even after the reset, the setup menu still read "SAT & ANT" rather than "SATELLITE." I then went into Antenna Setup, but saw no way to get rid of an antenna. Just to be safe, I reset the receiver again. Now that I am back in DC, my mother called me saying that when she is watching her shows, a message keeps popping up on the screen that something is wrong with her OTA tuner. (Obviously, since I unhooked the AM-21.) So how do you properly reset the box to uninstall the AM-21? Thanks!
