After the announcement of the above video finishes playing, the problem I have described will occur. Another problem is how to get Buffering MediaPlayer events, as well as his Buffer progress, I registered BufferingProgressChanged but not starting this event

At the moment, that link is returning:
I'll give it another try in a few hours.

It looks like that buffering event just doesn't want to work on WP8. There is some more information on the WP dev forum: MediaElement's "Buffering" state: WP7 vs WP8.

Out of curiosity, have you tried to see if the buffering event is still broken on WP8.1?

After yesterday, just a question, video address on the failure, sorry, I was trying to video into the software of my own play, but they seem to have been restricted. There is another way that you can get a good number of mp4 file segments, similar me3u8, but also the length of each segment, such as information, but before I try to play with Windows Phone Streaming Media, can not play. Is there a way to solve it?

Currently, I have not started trying to develop 8.1 direction

Could those be MPEG-DASH streams you are seeing? Microsoft already supports those with their Smooth Streaming Client.

With regard to the buffering event, one other thing comes to mind that I have been meaning to try at some point: if you sample the stream position and see sequential samples that are not increasing while the MediaElement is in the play state, then it is likely that the system is buffering.

I suspect that if you download that playlist and deserialize it, you shouldn't have too much trouble feeding it to the Player Framework's PlaylistPlugin.
