CD-Rs and CDs are quite different beasts, though they look the same.  The
technology is very different and CD-Rs are newer, which is one reason older
players don't handle CD-Rs very well.  This website has some great
information:

http://www.cdrfaq.org/

In a nutshell, CD-Rs use an organic dye while CDs use an aluminized
reflective layer.  Different manufacturers use different dyes.  Various
players may work better with one dye than another.  *Note: The same
manufacturer may use different dyes in different batches of CD-Rs.*  This 
is
particularly true of "off-brand" CD-Rs.  These manufactureres typically do
not make their own disks; they simply buy huge batches of the cheapest and
brand them.  Hence the dyes can vary widely even from the same 
manufacturer.

Fortunately, the "true name" of the manufacturer is on the CD-R.  Try this
program to read it:

I may have posted this info before so pardon the repeat if so.
