Answer 1

If any of these answers above don't work, and you're on an apache server, adding the following to your .htaccess file:

//most of the common formats, add any that apply
AddType video/mp4 .mp4 
AddType audio/mp4 .m4a
AddType video/mp4 .m4v
AddType video/ogg .ogv 
AddType video/ogg .ogg
AddType video/webm .webm

I had a similar problem and adding this solved all my playback issues.
