General Questions before committing purchase...

I have Dish Network and am planning on setting up a GBPVR system soon. I am guessing things would have been easier if I got a TV Tuner with a remote, but I decided on 2 channel streams instead. However, the USB-UIRT seems like my best choice now and needed some clarifications on this device.
1. Do I need anything extra to blast to the Dish Network Box? It is not clear if I need some kind of blaster cable or if the signal blasts from the back of the unit (or something).
2. How will this device work if I have 2 receivers (one for recording, one for watching)? I would assume my best bet it to use this for watching, then setup some other sort of blasting thing to control the 2nd receiver.
Thanks for your help. This project seemed easy until I got into the remote arena. Guess I should have took some baby steps and started with a single stream and a card with a remote/blaster setup.
