BigBox: Can't get videos to play in the background instead of showing the gameplay images

[RickBungle]

I've gone crazy trying to figure out why videos won't show as the background in the BigBox game menu instead of gameplay image.

I've tried everything I can think of: 

Switched from VLC to WMP

Tried different themes

Tried different views

Verified that I actually have videos

Anything else to try that I might be missing?  I've set this up on another system before and didn't have any issues getting them to show there.

In Big Box System Menu > Options > Video > Show Game Background Videos (or something pretty close to that). Turn it on to show videos playing as the background instead of in the forefront image/video view.

Yep, I have that checked.  I even tried toggling it off and on but it still only shows the gameplay image.
