After longer navigation in MediaPortal (20 sec of pressing up, down, esc keys) it freezes :/
And after freeze sound of clicking can be heared but no action is seen. In window mode I can see title of window is changing (eg when I press esc button).

I made clean Install of MediaPortal with no plugins and skins - the same result...
