This is probably more of an issue with XenForo but, if it is possible to implement it would be very useful. Basically just a way to embed other non-streaming websites, such as our own hosting. ie: Instead of using Youtube, which can pull videos (like that recent PSP beta), users could also use their own hosting and still have the video embedded in the post. hope that makes sense
It allows streaming from many popular video hosting sites, so why would you want to use your own bandwidth? Also, that would mean supporting many forms of video, whilst these sites dish it out in set format.
