Can you check your installed version of libavcodec51? That's one of the
things which d-m modifies.
Unfortunately, it is not my machine and I don't have access to it for a while.  I only had the machine for a short while which is why I had to do a fresh install and leave d-m out of it for now.  If I get a chance to check, I will, you're probably onto something...
