It's supposed to be able to play VCD's,
I've tried CD-RW and neither it
or my old Sony DVD player would read them.
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. 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).

Ah. Any idea what type laser is needed for DVD-R
then?
AFAIK, all of the DVD formats use a red laser for reading and writing.
Apparently the DVD consortium is NOT going to approve a new high-def
format using a blue laser (as proposed by the BluRay companies), but
is instead choosing to use higher compression ratios instead. I already
find the artifacts on current DVD-Video to be somewhat objectionable
(though generally not as bad as the noise on VHS tapes), so I'm not
thrilled about the idea of compressing it even more. While I'm sure
that newer compression technology will be somewhat better for the
same bit rate as MPEG 2, I doubt that it's really four times better.
