I have spent several hours trying to install the YouTube clone finding out several answers The most major problem is it will not run on Php 4.3 because of the ffmpeg-php installer . When trying to do the phpize it fails on Php 4.3 and produces errors. Another requirement is to have php-gd installed - not a standard package on RedHat or Centos. I have found a few  things that are easy to fix but very hard to get all together without alot of work. I will be putting a E-book together on how to setup the YouTube clone  on RedHat, Centos, & Fedora. The YouTube clone script can be downloaded from my site under the DOWNLOADS link. When the E-book is complete it will be on my webstore site

Pricing has not been set yet but the YouTube Clone is a free download
