Video File Size Upload
Ning To Jamroom
With that info my guess starts pointing towards the server and its ability to convert the video.
Both YouTube and Vimeo have a ton of processing power at their disposal to do the video conversion. What I suspect is that there is some sort of server limit on your account.
When a video is uploaded to your site, jamroom converts it into formats that are viewable via the web. For video that is:
* .flv
* .m4v
.flv is flash and plays in adobe flash player but wont play on some mobile phones (eg: iPhone ). and .m4v is for html5 players.
So when you upload a .mov file the server has a lot of work to do.
I suspect that firefox is playing it because it doesn't mind that the video is only half there but the other browsers are being more strict.
Take a look in your server's logs to see if there is anything that might indicate this is/is_not the case.
--edit--
We've got a system planned for cases like this that will allow you to out-source the conversion phase of the video/audio to some of our servers then pass back the finished playable version so you won't run into that sort of issue, but its a ways off yet.
