First, thanks for the help with my defective HR 20 that kept downloading software and reacquiring the satellite signal every 20 minutes. A tech came out and replaced it with a newer version. Here's a new issue. I have three devices to turn on when watching television: The TV, the HR 20 and a Bose audio system. I've been using a Harmony remote, which worked great when I had the same equipment but with an HR 10-250. I've reprogrammed the Harmony for the HR 20. However, when I use the Harmony, the HR 20 locks up. It won't turn on, even with the factory remote or by pressing the front panel button. The problem can be fixed by pressing the reset button on the HR 20. I plan to contact Harmony, but wondered if anyone here can explain why the HR 20 would lock up in this way. Thanks.
