When I burn a cd, at the finish the programme asks whether
I want the cd to play on any device or on that computer
only. If you want security for the contents it will only play on
the computer that you burn it on it, if you select this computer
only. It will not be read by any other device.
It you click on the any device button, then it
will play on anything without problem.
This may or may not be the answer depending on what burning
programme that you are using.
