I am about to upgrade to the VIP 622. If I attach an OTA antenna to it and do not subscribe to any local channels through Dish, will the OTA digital channels show up in the program guide at all (even in the high 8000 numbers)? If so, can I use the DVR to program a recording of these OTA digital channels? Finally, if the digital OTA channels do show up in the program guide and if I can receive OTA digital channels from two different DMA's, will all of the channels (from both DMA's) appear (for example the CBS affiliate from each DMA)?
