Xbian stopped buffering by itslef

[Avriukas2]

Oh no... After screen calibration it happens again. Then I restored original
guisettings.xml and buffering disappears. Now I comparing these two files
and cannot find any differences exept:

when buffering:
<resolutions>
<resolution>
<description>1920x1080 @ 60.00 - Full Screen</description>
...


when no buffering:
<resolutions />


I have no WiFI...
