(Neither does the beep setting -- unless you've got different hardware than I do.)
Presumably, BER stands for Bit Error Rate, but I've never seen it displayed anywhere. It would be the inverse of signal quality, but I've never seen any of the various signal quality indicators on different screens fail to show up if BER is set to off.
the file in the unit if it is not modified come with the euro setup unless you update it to the US file then that setting will disappear and all depends who writes the US file....
this is my opinion since mine I purchased it from the Openbox us site and it came with a modified file written here in the US.
I've used all manner of European firmwares and I've never found the beep option nor the BER option to do anything. As for the satellite list, I built my own a long time ago because I thought that the naming convention used by the manufacturer was ugly, so it no longer matters to me whether a firmware update comes with American or European satellites.
