Problems viewing on iPad and iPhone

Hello,
I can’t get my video to work on iPad and iPhone.
Its not a secret video or anything and is working fine on desktop browsers.
I have the following formats: f4v, m4v, mp4, ogv, .webm
as well as the .png poster.

Please let me know if I don’t need any of the above formats, and also how I can get it going on ipad/iphone.

Also: I set the video to Preload because the video wasn’t working in Safari, after I clicked preload it seemed to work better accross all desktop browsers.

Many thanks for your help and for creating this plugin.
