 There's a huge difference between a DVD player being able to play stamped
 VCDs, and being able to play CD-R.  Stamped discs can be read with the
 red laser used for DVDs, but CD-R must be read with an IR laser.  Many
 DVD players only have the red laser. 
Ah.  Any idea what type laser is needed for DVD-R then?

  You didn't say how old your Sony DVD player is. 
Their first generation
 players, the DVP-S7000 and DVP-S3000, have two lasers and can read CD-R.
 I've never tried CD-RW in my DVP-S7000, though. 
I really had to think about how old it is!  I got it about four years ago,
though the model had been out for a while.  IIRC, it was a midrange model,
and I think it was one of the second generation players (I'd have had a
first generation player, IF, they'd brought out the Star Wars Trilogy).
