I doubt you can. Look at how easy it is to copy DVDs, and that's with the multi-million dollar film industry's resources behind anti-piracy techniques! That is the problem with digital data - the only way to stop piracy is to alter the data, which reduces quality, like those "pre-ripped" CDs that you can't play on a PC, and sound crap.
VideoCD can't be copy-protected, it's just regular Mode 2/XA CD and therefor it can be copied with regular Windows Explorer if needed.
