Alright. I got this working on my PC. I have an iPhone, Android tablet, Fire TV, and use Plex for my media player.
5k Player installed on a PC get's you Airplay to the PC. It sucks. Locks up, closes, iPhone goes to sleep and the video stops. Airplay sucks. Period.
I installed a few Airplay apps on my FireTV. For some reason, the iPhone will not see them and didn't play at all. Maybe due to the iOS version. duh no. Old iPad worked but played audio only. Feck Airplay. I hate it.
Found the APK and installed that on my FireTV. Got excited, thought it was going to work. App opens. See crest logo, app crashes. Feck you too FireTV. You can kiss my iPhones ass.
Installed Bluestacks emulator on my PC. Installed APK. Watching MUTV on PC.
Blustacks quality is not as good as Airplay quality on PC but it's smooth. One thing I noticed is that I had to login on Android app. So create your MUTV account and login with that. iPhone let me trial. It also won't let you watch video on multiple devices so no sharing accounts with yo mate.
