	Ah, thank you, thank you.  I just can't see wasting so much of my disk 
	[and bakup disks] for what are mostly voice/lectures.  

	I suppose I can buy a DVD-R[W] and fnd out, but is there any reason
	why I can't have many hours of audio on a DVD?  In other words, id a DVD
	*only* for video?   --Might be nice to gather (parts of) my favorite CD's 
	onto one Very long-playing disk.

	gary
