Hi, I'm planning to get Dish Network with ViP622 DVR. I understand that the TV2 will be connected thru coxial and is in SD. My question is... The back panel picture of ViP622 in the manual, it says CH21-69OUT on the coaxial out. Is this mean I can only watch these channels on the TV2? I thought I could watch all the channels same as TV1 but just in SD instead of HD quality. Thanks for your reply.
