Medial element problem on Safari browsers- Windows and Mac [#1496912]

Hi,
We're working on a project were we had to put 10 videos on one page and make them available on both Windows and Mac platforms with possible coverage of all of the major browsers. After lots of trial and error we've managed somehow to make Firefox and Chrome happy, IE9 too, using the sample code with multiple sources on the homepage of Mediaelement.
On Safari browser. we have a strange bug- the video previews are loaded properly and all looks ok at first. Then if you click on one video it starts to play correctly and all looks fine. If we start another video the first one that plays is stopped but instead of playing the new one it shows the same first video only this time it's in the new player window. I don't know if it's an issue of the drupal module itself (probably not) but we could use some help if someone had the same problems with multiple videos on same page and can give us a clue.
Thank you.
