I never heard or saw a snooze button on a Beo5/6 before - I have both. But what this button does is working since years with a Beo4 (or 5/6) and a Lintronic box. There is a special feature called sleeptimer. Just press a number ( 1 for 10 min. - 9 for 90 min.)and GO in CLOCK mode . After that time the box will automatically shut down your audio/video turn down the light and close the curtain - whatever you programmed as a macro to the box.
I have programmed a GOOD NIGHT button for my Beo6: a very simple LIGHT - STANDBY command with one button, that shuts down my beo in the livingroom immediately, waits 45 seconds and turns down the light. In that time I can logout from Beoworld forum, take the glasses into the kitchen and leave the living room.
It also works nicely with the new LIGHT functions like LIGHT - MORNING, TV-VIEW, RELAX....
