	The source is just over 6GB.  bOth of my devices play them.
	k3b gave the exact number, but it is over 6.1 G.

	Ah, ok, this is what k3b put in /ust/tmp/kde-kline/foo.iso.  I
	decided to just-leave it for now. Only my source DVDs are around

	I'm going to have to man -t the man page and read offline.
	Looks like I'll need to compress the source. On Sunday, Michel
