Video URLs

Everytime I try to post a video, any video, from youtube it always says "Video Not Found" or if I try to add a video to my videos I get a HTTP 500 Internal Server Error. It's starting to really really annoy me since I'm adding videos to games that don't have any.

Just tried to post a video and it worked for me, is it still not working? Please can you post the video url you are trying to add.

I just tried to add a video and it worked it must have been my internet connection or something. Sorry.
