Movistar Fusion Tv Language problem

[Biggles]

Just had the Fusion Tv installed today. Seems good for free.

Does anyone know how to permanently set the idioma of each channel to VO.?

If you change the language you can hop between channels and it will remember your chosen language but if you switch the box off (which I'm likely to do when not in use as otherwise it'll be using up bandwidth downloading whichever channel it was left on,) then switch it back on it forgets all the channel settings for languages.

Anyone figured this one out?

I'm not clear what the difference is in bandwidth terms between downloading and streaming.

Surely streaming uses up bandwidth?
