Xbox 360 won't find videos

[Akai]

I have my Xbox 360 stream videos from Windows Media Play 11 (which had videos in the library from my external hdd). Well it's worked every since I started, but just like two days ago, it stopped working. My Xbox just comes up with "No videos found, see if.....etc etc". I mean wtf, my external hdd is a NTFS (which supposedly isn't supported by xbox, yet it worked). And my external hdd is attached to my computer. I can't get my xbox to find my video files in the Media Blade (Media>Videos), the Media Center in Xbox finds it, but the standard dash can't.

So, what the hell? It's really pissing me off.
