Solving playback issues

[asdfasdf1234]

The unit streams for a 20 min-1 hour then it crashes. I have to press the Home button and go through all the button presses to locate the channel I was watching.

Twice, the unit froze when I tried to adjust the volume. 
Once, the program just stopped playing.
Once, Netflix reception stopped.

Check connection tested ok.
