You used to have to use a program to upload your advertising videos to the CF cards.
Then you would insert the compact flash card into the side of the iView unit.
It would then play the videos over and over on the lcd screen.
I made an video for that large gaping empty hole in a WMS BB2 for someone once.
It was for someone's "Mancave" with various graphics.
Fun little video toy to play with, if you have the right equipment.
I don't remember if I kept the Bally Video DL Manager...I think it was on a laptop.
I'll have to look for it.
