I cannot use MP4 because AOO does not support MP4 files.
I can use AVI or WMV and either works fine in AOO ... but LO 6.0 does not play the video - it just plays the sound.

Any suggestions?
One thought is to put a link in the presentation where the link points to the video file and plays it. Has anyone got that to work?
Or is there a video format which both AOO and LO support where LO plays the video as well as the sound? There are on-line sites where you can change (almost?) any video format into any other.
