The way I've heard it, many older CD-ROM drives can't read CD-RW media, the re-usable disks which cost about $10 each rather than CD-R which are about $2 each. [It's pretty much impossible any more to find a CD-R writer that can't also write CD-RW disks.] So the first key to writing disks to be read is to use CD-R and not CD-RW media. The second issue is that most CD-R recording software defaults to closing a "session" at the end of writing a bumbh of stuff, but doesn't close off the final disk structures until told to do so. In Adaptec's EX-CD Creator Pro, I have to flip to an options page when I make a CD and select "Close Disk" instead of "Close Session" to get maximum compatibility with older CD-ROM drives.
