For my menu background, I loaded a video and audio file (converted to MPEG2 and AC3, just like the main video and audio) and it automatically put a check mark in the "Motion Menu" check boxes. But, when I tried to preview it, it just gave me a still background image from the video. I went ahead and burned it that way and the menu and audio works, except for the motion part. Apparantly it accepted it as a motion background, so why does it not move?
