Firefox "Error loading media" issue

I've just upgraded jwplayer to the latest version (7.7.4) but am sstill having problems in Firefox - video starts playing, plays for a few seconds and then stops with an error message "Error loading media: File could not be played".

I have checked my htaccess file for mime type and it seems to be correct. Here's what I have:
AddType video/mp4 .mp4 .m4v
<IfModule mod_mime.c>
AddType video/x-m4v .m4v
AddType audio/x-m4a .m4a
AddType video/mp4 .mp4
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
<FilesMatch "\.(mp4|flv)$">
FileETag None
<IfModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"

I've checked Headers in Firebug's Net panel and the file says "Content-Type: video/mp4"

I've seen an older post mentioning Renaun tool to fix any encoding issues - I tried it but it said it found no errors.

What else could it be, what am I missing? Here's a link to the site (warning: adult content) -

HI there,

The video and player are working fine for me in Firefox 50 on macOS Sierra 10.12.1.

What version of Firefox are you using when you see the behavior and what operating system are you using?

Thank you.
