i have a 722 DVr dual tuner hooked to 2 tv's plus an ota antenna to the antenna input. My digital ota stations show up in my chaanel list and on all HD list. Is it possible to record an event off the ota station while watching different stations on satellite tv 1 & 2 ? I can select OTA off my Samsung Tv remote source button and watch the ota channels while recording off the satellite feed on TV 1 but watching the satellite channels on tv1 while recording ota is confusing me. If this is possible please point me in the right direction.
