It should be noted that, if a tuner is free, if you hit record on the HR24, you can then pull up the program on the other receiver from the "list" button. So you can access OTA channels from the other receiver, just not easily or directly from the guide.
just a clarification. If you have an AM21 attached to the HR34 genie then attached CLIENTS (C31s) can see OTA channels directly but not any other receivers /DVRs. Those can see OTA recordings via whole home as ejb1980 has posted.
Good point. That is the sole reason I am upgrading to the Genie/client set-up instead of my current HR24/H25 set up. The CBS station I receive via Directv is laughable but the neighboring DMA's CBS station is legit (and stronger OTA here than my "local" one...). I miss the subchannels in the bedroom, too.
Thanks for all the great answers and suggestions. My two year contract is up this month. Is there any chance I could get an upgrade to a Genie and a Client for signing another contract?
