  How fast the data was recorded shouldn't affect whether you can read
it (few CD-ROM recorders write faster than 4x, anyway).  But there are
at least two options supported by many/most CD-R recorders that may not
be supported on older drives:

1.  CD-RW media
  I'm told that many many CD-ROM drives have trouble reading these
disks.

2.  Multi-Session
  This allows for later additions to the CD, so it's the default for
many CD-ROM recorders.  But some older drives may not understand how to
find files from more than a single (probably first OR last) session.
