Hello.
I use these plugins.

1. Sliders
https://www.nonumber.nl/extensions/sliders

2. Tabs
https://www.nonumber.nl/extensions/tabs

3. HDflv player

I give you, and a demo page.
http://www.greekplay.gr

When I open the page, videos and upload them in turn (tab 1).
The problem occurs when you change tab (tab 2).

When I open the tab 2 stops video playback. When I return in one tab, video upload over again, as if opened from the start page.

This problem does not occur in IE9, IE10 and IE11.
The problem occurs in firefox, chrome, safari and opera.

I contacted the developer of plugins that as I mentioned could not identify a problem from the side.I suggested to contact with you whether the problem is in HD flvplayer.

info:
Joomla 3.4.1
Flv player 2.3

If you need to access ftp and administrator, tell me to send it by email (you will indicate me).
Thanks.
