Official support for the scripts is via the contact form. The forums are more user 2 user based support.
I try to help and reply when I can, but the issue you pointed I do not think is a problem with the media player plugin, it is a problem with jwplayer and/or chrome. But your post is very difficult to understand, I guess that English is not your first language.
If you want to continue discussing this with me then pm me, if you are not happy with my responses, contact Adam via the contact form and complain.
