have you selected the right switch settings on the back of the box?
I am having problems with the hd settings
the dashboard says the cable is set to tv
but have component cables on the cooler king, non microsoft,
and on the menu cannot seem to set to 720p
as it reverts to 480p
Just found out that I have to return cooler
It seems that this is a problem with the 1st version and m2 version is ok
