As it turns out quite a few people seem to be looking for a solution as to why an FLV file won’t load correctly from a cPanel hosted account. For the most part webservers won’t serve a file it doesn’t know about. The problem is in the MIME type setup, and here is how to solve it.

1) Go to your cpanel and look for an icon labeled MIME Types.
2) For MIME Type enter “video/x-flv” (no quotes)
3) For Extension(s) enter flv
4) Click Add

You should be all set!
