Hi, I've heard that it's possible to add MP4s or AVI files to
Illumination Software Creator by using 'Custom Blocks to add this functionality'... but that it requires 'a little bit of down and dirty coding to make happen'. I'm trying to find out what kind of coding this person might be referring to, which, at present, they don't seem inclined to elaborate on.

Maybe someone here knows. If so, I thank you for your time and help.
