If you want to play from beginning to the end, you should send 0-, not 0-end.

I think the problem is that we are not distinguishing the timespan of the 
underlying media, obtained from the description from the timespan of the 
current play request. I dunno if it is a VLC bug, live555 misdesign, or both.

Step 3 is correct indeed - but step 2 is correct as well.
