There is
no way to produce a
standard compliant VCD that can't be copied! It could be possible to deliberately introduce errors thru softwares, which the VCD player would normally ignore but CD ROMs wouldn't.
On a side note, Sony (I think) introduced some DRM technique in a similar manner. But failed miserably. But they are still at it, come up with yet another lame idea recently.
Bottom line? If the video can be seen, it can be copied! Anyway why bother with so much protection for a VCD?? Try DVD they've got better encryption CSS. But unfortunately you can circumvent that too DeCSS
