Besides trying to figure out what IPTV service provider to use I am experiencing technical oddities. So I got a Formuler GTV and hooked it up into my Sony AVR. Using the same service provider using M3u link into tivimate and also into mytvonline2 apps. The tivimate one does not seem to let through 5.1 sound whereas mytvonline2 does... exact same movie by exact same provider. So it seems depending on what app I use on the box I may or may not get 5.1 sound (if the source has it of course). The GTV box does not seem to allow RAW/Passthrough of the sound to let my AVR handle all of that instead of the box... I think this may fix the issue but not sure... so I think I will dump the GTV and get Nvidia TV instead... anyone have experience with this kind of thing and think that will fix it? Also, using the Amazon Prime app on the GTV, when the content played is 4k HDR it comes out very washed out image in TV... my TV and AVR can handle HD10+ and Dolby Vision etc... so I don't know why this is happening either. My Firestick is in the same AVR and the image is just fine. I have been at this now for about 12 hours over the last couple of days and ready just to take advice on what is the best thing to do. I don't like the Smarters app interface. So looking for one that works on Nvidia Shield TV, good interface, process HD/FHD/UHD image and 5.1 sound etc correctly. And recommendations of a good content provider of live (mainly uk) and vod (in English and big choice) to stream FHD/UHD.
