I have a VIP 622 HD DVR box. Is there a way I can connect my over the air antenna to it, so that my DVR can record from it? The main reason is that although I pay for my local channels, I can't get the CW HD on dish. However, I do get it with the regular over the air antenna. Is there a way I can get CW HD thru the antenna on to my 622? Please walk me thru this, if it is indeed possible.
