I called this morning to get another receive added to my account (612). So I thought since it was already going to be extending my contract, that I would upgrade one of my 622 receivers to a 722K. I'm just wondering if I should expect anything different (good or bad) with this upgrade. I use OTA, so I'm also getting the OTA module which will give me another tuner for recording locals which I need. Will there be much difference between the 622 and 722K as far as menus and screens are concerned? Is the OTA tuner for the 722K as good as the tuner on my 622 I'm currently using?
