They work fine with mplayer. That sounds like a Microsoft "solution".

Yes. This is as described in the wiki. Comparing to what happened
before I had this file (exactly the same problem), I don't think it's
needed at all.

Why the --disables? Does it work if you don't set them?

That might stop it from searching in other places (it looks in
/usr/local somewhere first), so I'll probably set it once things are
running. Since it's finding the library, this difference isn't the
cause of the problem.
