video play doesn't not work

I recentrly received some emails of people telling me they
were having problems with the play functionality of the module.

I firts thinked that they did some misconfiguration but they still
not been able to use the module.

I then decided to look back to the video.module for 4.6 (which was
a little forget during the work for 4.7) and understood that the
play feature of the module was broken.

I still did not understood why this happen.

Attacched there is a video.module file which works, I will commit it to
cvs after some positive feedback about it.
