Newbie question...I'm going to be traveling for about six weeks this summer, and so I'd like to put my DTV service on a vacation hold. There's also a couple of shows I'd like to record over the summer that are network shows. Is it possible to use my AM21 to record OTA shows on my Genie without having active DTV service? Or is all recording capability shut down when I pause my service? I haven't tried a hold before, so really wasn't sure what worked and what didn't. Thanks for the help!
