I've noticed through several providers, HGTV on weekend mornings is just the screen saver of a firestick/roku. I find it strange that whoever is providing the stream doesn't keep their device awake. Also find it weird there isn't a better way to do it lol. IDK just wanted to rant..
I noticed the same thing last night. Investigation discovery was a Verizon fios Screensaver on vaders, and had the wrong channel all together on my groupiptv.com account. Both working back late last night.
Most providers have a bunch of cable set top boxes or hacked cards going to a hdmi to iptv box. Several of them can be found from China via alibaba or the like.
