You would think, but from what I found when researching why mine couldn't
play CD-Rs, it is actually VERY common for a DVD Player to fail to play
CD-Rs, but plays a CD-RW just fine. So common, that apparently, it is the
norm for a DVD Player that can play home brew VCD's will only work with
CD-RW, unless is specifically mentions that it works with CD-R. At least
this was true a few years ago when I was looking for info.

And beyond research, in my informal polling of friends and their DVD
players (mix of old and new models)... I found the fact holds true. Out
of about a dozen DVD players I have ready access to (ie: I can go to
someone's house, and try a disc). One could not play any kind of VCD. Of
those that could, I think there were 3 that only played commercial
stamped VCDs, the rest could play home brew VCDs. In all cases where they
could play home brew VCDs, all could play CD-RW, and 2 could play CD-Rs.
The two that could play CD-Rs both specifically mentioned that they
handled CD-R media. One was a multi-format, multi-region unit, and the
other was a brand new one that even did MP3 audio CDs (which was kind of
cool).

And interestingly with one player, it had problems playing discs created
by my computer, but no problems with one created with my VCD burner (it
could play either, but the computer made one wasn't recognized every
time... sometimes you had to eject the disc, and reinsert it a few times
before the DVD player would accept the disc).
