Shouldn't be a problem. Buffer underrun protection (burnfree) is enabled
automatically on all burners produced nowadays even if the burnfree
driver option isn't set. It's really just there for people who for some
reason want to turn it off.
I guess you get those warning because a straigh CD to CD copy without
creating a temporary ISO file will put a lot of load on the I/O system.
