This script uses youtube's api which allows you to pull millions of videos from their site to yours. Using the admin panel you're able to only display videos for a certain category. For example if you would want the site to only show muscle cars then your site will only show muscle car videos. This is just one feature in a huge array of other features. A few other features include built in sitemaps, video comments, cloud tags, ad preloader, many different layouts and so much more. Best of all though is this script is 100% upgradeable. When ever a new version of the script is released you get an email with a download link to the new script. Same thing with new layouts their all 100% free.
