MK2 volume - MAC address

Hi, just received the MK2 (big thanks nice unit) and I'm just syncronizing via the LAN which is cool.

Now while playing with the thing a question came up, don't know if this is a bug. When going into e.g. the 'dimmer' menu, while turning the knob right, the brightness goes up, lets say, from 50 to 60%. When I release the knob from turning, brightness goes down one level. Same with volume. Also, I have noticed when turning the knob slowly, e.g. volume doesn't go straight up or down, but goes up while jumping back low one level inbetween. A stupid explanation, but I don't know if how I could do better.

Thanks again, J.

Sorry I fogot to say, it would be cool if the MAC address would be printed somewhere outside, J.
