The problem isn't present with Xine.

 From what I saw (googling the error message), that particular message
seems to crop up for several different and unrelated reasons.

Ok.  Noted.

I had the Intervideo driver because it came with that particular install
off-the-shelf.  I just wanted to double check against how Windows
performed.  I'm not looking to enrich the Windows environment.  I just
wanted something to use for comparison.
