Apologies !
Results for the 6 Beo5 Screen options provided are as follows:
{BouQuet +} = does something like a page up or page back but could not correlate directly to DM500 Remote Function
{BouQuet -} = does something like a page up or page back but could not correlate directly to DM500 Remote Function
{POWER} = Red Power-On button on DM500 Remote [SUCCESS]
{Dream Menu} = Vol - / Left button on DM500 Remote [SUCCESS]
{UP} = OK button on DM500 Remote [SUCCESS]
{DOWN} = INFO button on DM500 Remote [SUCCESS]
Note that no other button on the Beo5 wheel produced any Remote function
I have attached a screenshot of the DM500 Remote for your reference.
