[18:19] <Jay2k1> my mythbox is connected via hdmi to my amp, which is connected via hdmi to my TV. when the mythbox boots and amp and TV are off, resolution is ok (1920x1080) but when i switch on TV and amp, it changes to some really low resolution, 640x480 or 800x600. how can i prevent that?
[18:20] <Jay2k1> actually it is 640x480
