there nothing wrong with mediamaxx script, it can handle alot of traffic.
you can look at one of the sites I owned tubefreaky.com which pornhub tried to get me over.
http://www.adultvideoscript.com/ this is clip-share pornhub clone and it has alot of user friendly tools, it comes with Multi-Server System which mediamaxx does not, you have to pay another 100 for it. adultvideoscript support is way better, both slow at times.
