It is located under "Files & Media", the Under "Media Providers"
and example of what is under mine:
Media Providers
Description Media type Action
DISH Harrisburg Harrisburg Satellite 170 LiveTV Delete
DISH Harrisburg Harrisburg Satellite 170 LiveTV Delete
You will be presented with a description and a media type, in my description it says DISH for dish network, and the type of programming. The media type is LiveTV.
However if it is having issues downloading from schedules direct, I would suspect you "Internet facing" NIC connection. I have seen this error before, and it was because I had a bad cable on my outward, internet connected card.
Just food for thought.
Best of Luck and Regards,
