I connect OTA to both 622 and TV. That allows me to watch Heroes live on TV and record 24 on 622.
You should be able to watch Heroes and record 24 and record something else at the same time with the 622. It has 3 tuners.
...............or am I missing something?
I know on Mondays I record 3 different programs at 9pm with my 622 and if I were home I could watch the items I recorded at 8 while they were recording at 9. The 622 is the only reason I stay with E*.....well that and the HD leader and so forth.
I guess I could put the HD locals on my TV instead of the receiver and then I could cancel my locals with Dish Network.
