Fix User/Group Cpanel issue and set up 10 missing members on Boonex siteb

Recently a number of videos aren't visible on my site. I've been advised that it is a group/owner issue. I'm looking for a programmer who can fix this. Also, I'd like the first ten (1-10) members assigned for company personnel and would like this set up. This project is also an opportunity for a programmer to familiarize themselves with the coding so that they will hopefully be available to assist with additional more challenging needs in the future. Regarding the site it was built using the Boonex Dolphin 6 platform, using PHP & MySQL. It has been customized significantly. The video system utilizes the Longtail JW Player.
