Carlos Moreira on "video player with preview"

Hello.
I think that to work on mac products you'll have to go for a html5 solution, like this one for example: http://wordpress.org/extend/plugins/html5-video-player-with-playlist/ But the question about the advert before the video starts might be the more difficult part. Maybe you have to check other solutions. You can ask the author of this paid plugin if it's possible: HTML5 Video Player.
