MechBunny Cam Aggregator is another product developed by Konrad, the developer of MechBunny Tube Script
Because Cammixer is not required to be used as a standalone website, it offers better flexibility for integration with an existing WordPress-powered site for extended functionality.
Updating is much easier as a WordPress plugin, than the cumbersome updating MechBunny requires (downloading a zip file and manually typing-in and opening page in browser), so again, this point goes to Cammixer. There’s even Auto-Updating of plugins available in WordPress, so it’s not even a question which has the better option.
You’re not tied to using only a couple themes developed by the original developer, as with MB. With Cammixer, you can choose any of the available 35,000 themes in the WordPress repository, or any of the awesome premium themes available.
