Up through version .10 (I think), there was a patch for mplayer/mencoder
that let it read myth .nuv files properly (myth's nuv files aren't
standard nuv files - Isaac extended the format).  After that, there were
more changes to myth's nuv files that broke the patch's compatibility.

If this works, AWESOME.  It hasn't for most of us in the past.
