how do you play videos in ITG arcade?

Hi,
You know how you can play stepmania songs in an arcade on an actual ITG machine with a usb. Well I can convert the songs to play there, but the videos never show up. So I was wondering what should I do to make the background videos play on the ITG arcade machines? Is there a way? Thanks a lot!

R21 and up only reads the step information and not the BG changes. Anything beyond it are hacks, and not meant to be discussed in this site.
