So after I told my reapair guy yesterday that I didn't like the lack of OTA with the HR21 he said that the way to get it replaced with an HR20 was to call DTV and tell them the HR21 was not working. He said that in all cases he heard of, DTV will send a refurbished HR20. According to him since they dont' make any more HR20 they now only use them for replacement. Anybody heard or tried that? Thought about doing it so that I can have OTA again. Not sure I want to wait till march till the external OTA becomes available for the HR21 (for a price, of course!)
