Paul,

You said it was a CD-RW that failed in an older drive.  Did you
try a CD-R (no W) in that drive?  Some older drives can't read
CD-RW media and it looks like that's what may be happening here.

As an interesting side note, pure DVD players (like my Sony
at home) cannot read CD-Rs.  Apparently the material CD-Rs
are made of is invisible to the DVD laser (different
wavelengths).  CD-RWs, however, use a different material and
will play fine.  This manifests itself in that I can't burn
a VCD or music CD to CD-R and play it on my DVD player, even
though it will place regular VCDs or music CDs.  If I use
a CD-RW, though it works.  Apparently, computer and new
DVD players get around this by including 2 different lasers
in the drive (1 for DVD, 1 for CD-R).
