Video Suddenly Stops Playing

[CalebBrown]

The videos on this channel suddenly stop playing:http://www.livestream.com/janaschi
Every time I watch a video of hers, it'll play for a while then stop. Then if I try to skip forward or backward the video might start playing again (for about 2 minutes or less and then it'll stop again), or it will buffer but never start playing again, or the end screen will come up (you know when the screen darkens and the replay button pops up).
The time on the video stops too, so it isn't a problem with the recording.

Hope someone can help.
