I have. It works as long as the block size isn't odd. Generally
any cd will take a block size of 2048 bytes, however, if the CD
is "bad" (scratched, or what not), a smaller block size (1 ;) may
help you get more good data at the expense of some speed. You
can also use the conv=noerror option to ignore read errors if you
really want whatever data you can get.

As somebody else mentioned, cat works too, but it doesn't have
an option to make it ignore read errors and keep going.

Otherwise, you're right, use mkisofs, or mkhybrid to make a
filesystem from some of your files, and then use cdrecord to burn
it.

There is another program (cdwrite?), but I don't think it has nearly
the same level of device compatibility, not to mention that the
number of systems cdrecord will build for is very impressive.
