[mythtv] quick patch for xmame 0.62 segfault

[Todd Malsbary]

I see this problem has been run into before, so here's an actual patch for
it against mythgame in cvs.  The first change is to fix the segfault that
happened, and the second is to use the correct argument name for the
screenshot directory.  I don't have 0.61 or less to test it against, so
hopefully it doesn't break anybody's setup.
