.mov not supported by browser, but no error message shown

[CorneeldH]

As we know, not all browsers support .mov. However, in Chrome at least there is no error / warning message, but the play button simply doesn't work for users. Therefore it appears buggy.

Could the app register the browser and show an error message when opened in Chrome / IE / etc. Something like "Your browser doesn't support this file-type.." Thanks!
