Okay, this looks like it's leading somewhere.  Here's the output from 
dvd+rw-mediainfo:

Now I don't know squat about what that really means, but some things 
look pretty weird to my uneducated eye:
Track #1 -- invisible?  It's the right size though.. but what does 
invisible mean?
and State of Last Session: incomplete?  err...  huh?  How do I complete it?

Thanks a ton for all the help so far.  Maybe these discs are salvagable? 
  Or if not, maybe at least I'll learn whatever it is I'm missing at 
this point.
