copy protecting vcd

[apalling]

I wanted to know if anyone out there knew of a way to copy protect a vcd so somebody could not make a copy of a vcd I made. Is this possible? I know no solution is perfect, but is there a way that would make it more difficult? I know of the site cdmedia world, but could not find software on there that would do it. Also, if i applied some sort of copyprotection on there would the vcd still be playable on a vcd player? thanks for the help.
