No problems with my T1, although I don't use mx, I use VLC or Android Player that's built in. The other thing I use is fast reboot app. It closes down all the apps in the ram. I use this before starting up different apps so it doesn't lag
Thanks a lot...Will look into getting a dreamlink
Android boxes are much more powerful than MAG which are made for streaming and are of pretty poor hardware spec. compared to Android boxes. You should have no probs on Dreamlink or even a decent Android phone for that matter
