I've had the Navi-X Script on my xbox for a while now and have also had the Youtube script on it too. It always worked fine and every once in a while when I go to play a video on youtube (either through navi-x/youtube or directly through youtube) it would pop up an error in the little white box saying something real fast then saying "Not a URL..." then it wont play the video. It still plays all the shoutcast stations and all, just having trouble playing youtube videos. Now, it NEVER works on youtube videos. It still shows a preview of the video and all but gives the error "Not a URL.." after trying to play it. Whats up with it?
