mine are the exact same way too! apparently,there may be some work going on to the servers again. myself,i am hit or miss with using the emulator. some days i can watch with zero problems others i have looping and freezing,but,i ( like some others here ) am waiting patiently for the service to get back to what it was when we first started watching it.
If you use MAG 254 though I have not tried the other MAG boxes .On your remote the bottom left button you have 5 options to choose from after each button press.This is another way for your aspect ratio.Try it
