I'm not sure when, but sometime between the time of this thread, at the end of September, and now, Oct. 27, so in the last month, Dish has upgraded the software, and you can now use a HopperGo with a PC. Getting ready to be gone for a week, so I finally got the HopperGo set up. When I looked online for instructions, they included instructions to watch programming on a PC. I should have checked that a week ago, I now have 2 methods to stream the files on the HopperGo to a TV by HDMI. Either through my laptop, or though my phone, which is a Samsung Note 8, using a Dex Station. The Dish Anywhere app is not optimized for the Dex, but you can also use the device to mirror the phone's screen, and the app works great in that mode.
Anyway, I don't see that any other thread has mentioned the upgrade for use with a PC in the past month, so I thought I'd share. It certainly makes the HopperGo more useful, in my opinion.
