Music Video As a Backdrop to Audio

[ddouglass]

Joe the problem there is that WMP is already providing the music as well as the visuals. WMP does have a slide show add-in for the visualizations, but I believe it is for still photos only and not for video.
To answer one question yes the Instabuttons does have volume control per file. Select the file to adjust, set the level you want and play to see if it is right. In the case you are talking about turn the volume all the way down for that selection.
