If the source is an ISO image (or other image formats), you could use
ImgBurn to burn+verify.

If the source is a set of folders+files, I am using TreeComp.

"A burned CD/DVD" *is* a file. At least on reasonable OSes. E.g.,
did you try \\.\M: ? If Windows does not support this, one can just
make an ISO image from the disk, and use FC (or diff).

Hope this helps,

P.S. In my experience, byte-per-byte comparison is not relevant. At
least, I never saw a disk which could be read byte-per-byte, but
the result would differ from what it is supposed to be. Disks
with some unreadable sectors - a plenty (a hundred?); but if
fully readable, then correct.
