Not sure I was being clear. I wasn't referring to music or music content but movie or music modes. I think the only really easy way to change it is by using a 818 or AC200 unless using an 861 where it changes automatically.

Instructions from a helpful dealer.


Start the Meridian Configuration program.
Then in the Config program open the 'Control Window' (just to the right of 'Store' on the top toolbar.

This opens the 'Control Window' popup
Use the 'Command' tab
The Command will default to 'ID'
Check you have your correct Com port (PC specific) and then Click 'Send' to check the connection, the DSW should respond.

Now to change from Music to Movie type in the Command Box (where ID was), and press 'Send'
For Movie: Mm MO (Then 'Send')
For Music: Mm MU (Then 'Send')
For Speakerlink control (default): Mm SL (Then 'Send')
