I can play html5 embedded video ogg media .ogv in an html file locally on computer with FireFox 3.6.8 but not when online. Apparently this is related to server side issue with incorrect configured mime type. There is no expected fall back to Flash but instead a black video box appears with x in the middle(some kind of error signal).

The issue concerns Yahoo small business web hosting but so far no support is forthcoming it seems.

Any suggestions would be helpful.

The server needs to send the .ogv files with the correct MIME type.
