If the video files are being stored in the private area, in Safari (on windows & ipad), it loads the image and when you click play you get the spinning wheel. The video never plays.
The video work just fine on Chrome, Firefox, IE 7 - 9 (all on windows.)
I can't link you to site because its private videos and requires a private login.
Any suggestions what to look for?
In the .htaccess in the private folder I added the following:
AddType video/ogg .ogv
AddType video/mp4 .mp4
AddType video/webm .webm
