Video Playback on Chromebook

Anybody have any issues on video playback using Chromebooks? It works great on every device I have tested- but I  have been getting some feedback that video is not playing on some Chromebooks with this message: "Sorry this video cannot be played on this system" I have heard Chromebooks are riddled with problems so it could just be the hardware...

I am pulling the video in from Vimeo and attaching it a symbol:

var vimeovid = $("<iframe/>");

sym.$("video").append(vimeovid);

vimeovid.attr('type','text/html');

vimeovid.attr('width','818');

vimeovid.attr('height','460'); 

vimeovid.attr('src','http://player.vimeo.com/video/12345678');  // url/Video_Id

vimeovid.attr('frameborder','0');   // 1 | 0

vimeovid.attr('allowfullscreen','0');   // 1 | 0

thanks!
