Running the script with "sh /media/dvd/install" or ".
/media/dvd/install" will work as long as the script does not invoke
any other scripts (without "sh" or ".") or binaries in the same DVD,
at that point it will fail due to the "noexec" mount option. This is
probably what happened to you, and you interpreted that as the script
not being able to run, while in fact it was running, only the binary
it was calling was unable to run.

I agree with Dave that the general solution to this problem (running
software or installers from media) is to remount it with the "exec"
option.

HTH,
