If it hadn't scrolled off the top of the xterm I'd have it!! I was looking
for debug options, which I can't find, or some sort of dry run option.

I've just started another session, all defaults, in a few hours when it
gets to the failure point I'll report the actual error.

     Theo and Elaine decide to settle by building a house sourced from all
     the world.

Thats the latest stable Gentoo version - media-video/ffmpeg-0.5_p20373 -
to give its full emerge name and version, so I guess that falls into the
0.5 and above category.
