Hallo Eduardo
You wrote the Super Video plug-in? Now we know the man to ask about videos!
Now the "original OP" is back in the H5P forum with your partial solution we can concentrate on the new OP's issue which I renamed VideoTime Pro not ignoring Prevent Fast Forwarding & Resume Playback settings in Workplace, because it has nothing to do with H5P. So, you think it is a player problem, not one of the web server? Otherwise swapping the player won't help. I think, I should check myself, rather than always asking. I'm a video ignorant and will remain that way, as long as I don't test the various theories. ;-(
