MAG box users : If your Internet connection is not stable , you can increase the size of "Buffer size". This will reduce the incidence of " freezing " the picture caused by the lack of speed, but will increase the time to switch between channels . Do not increase more than 2 seconds - if 1 or 2 does not deal with more value will also be fine , but will have bad side effects (hard switching ) . In this case you can increase the speed of the Internet .
