Has anyone made *any* of the supposedly VCD-capable stuff in graphics/ work
on NetBSD/i386 1.6.1?

graphics/[g]mplayer appears to be the most well maintained for this purpose,
but attempting to use that (via VCD->Open Disc menu item, and /dev/cdrom
symlinked to /dev/rcd0a) produces the following output:
