I thought about your point about the all-region DVD and realized it 
didn't make sense that it wouldn't read.  So I tried another DVD from 
the series and it had no problem.  Then I went back to the original DVD 
and it also had no problem!

The only thing I can think of at this point is some strange interference 
from VMware.  I found one such mention in (I think) a Fedora forum.  At 
the time of my earlier problems, VMware had been running and had grabbed 
the DVD.  I *had* then disconnected it from the VMware guest, but....

At this point, I can't duplicate the problem, with or without VMware 
running, so I don't know. what to think.
