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.

Trying to use CD-RW is asking for trouble. They have a lower contrast
ratio than CD-R, so even DVD players that can handle CD-R may not be
able to handle CD-RW.

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.
