Why won't my channels load

Hi Guys,

I'm new to this forum and a complete novice when it comes to setting up and using an Android box, so please bear with me.
I am on my third Android box and it seems sort of ok for watching tv channels, but if I try to stream a movie or an old tv series I can find them ok but when I get to the screen displaying all the links (gorillavid, filenuke etc) virtually all won't run. Am I missing something or is there a setting I need to look at. I have tried different sites (Primewire, Mashup etc) and all respond the same way.
I am currently using a Q7V box and living in Spain. My internet bandwidth is 20Mb so I don't think that is a problem.
I hope someone has some guidance.

Tony
