I had heard that Pro HD allows for one channel to be watched at home and a different channel on the mobile device at the same time. Is that the case? Also, do we have to have the TV on at home for the remote device to work? Sorry for the rookie questions, but I'm looking to purchase and want to understand some of the details.
The Pro-HD has a built in tv tuner. So, you can receive one channel through your tv at home and another channel through your Slingbox tuner. If you have a cable box or satellite box, you can only watch one channel at a time from the box. You can watch it on both the tv and through your Slingbox at the same time.
