I know you didn't mention .flv - The trouble is getting the video into .swf format. I couldn't get .mp4 and .ogg containers to work in Internet Explorer. I got it work in firefox as .ogv format. The only trouble is with Internet Explorer.

You have to admit the number of containers and browsers in which to read them is mind-boggling. I don't mind being patient and do the coding myself so I appreciate yours.
