Boxeebox and mk808

[chali]

Hi

I have a problem that looks like this,
When I stream to a boxeebox with 1000kbps
It looks really good.
but when I stremar to a mk808 (google tv android 4.1 minicomputer). It looks really bad, I have the same bitrate (1000kbps) and it is the same tv that I have them linked to.

Is there  someone with an idea how i can get the same image quality to mk808?
