Do not burn a new CD in a different format. All modern formats are already
supported in
the Mac CD driver.

You must turn on several extensions on your SE to make them work. These names
are from
memory, so please try to be kind:

Foreign File Access -- this is the master extension that enables those listed
below
ISO9660 Access
High Sierra Access
PhotoCD Access
UDF Volume Access
Apple Audio extension

Extensions Manager is used in later versions to move these files back and forth
from
Extensions to Extensions (disabled). Then a restart makes them part of the
working
system.
