Hello, and sorry you're having problems.
Here's the thing, if you have a DISH with two feeds coming from it, you still need some sort of satellite box to decode the dish signal- the Panasonic cannot do that, it contains a very basic cable/antenna tuner. So you will still need a satellite converter box and then can feed the converter box to the Panasonic.
So while you can still use the Panasonic for recording and playback to the TV, you will still need another box that connects directly to those two coaxial cables coming from the DISH- the Panasonic simply will not recognize that signal without another Sky Box, or other form of converter box connected "Before" it.
So the signal chain needs to look like this:
DISH------->Cables to Sky or other converter box----->Panasonic----->TV.
