DVD-R copy protection

[taos]

Then, a lot of protection tools are ilegal too (hidden sys, crash system options, monitor your apps,etc...)... :-)
I know that, but this can be an offtopic, and is very far from how coding the protection.
Home made video DVDR copy prot. is only (in my case) for hobby. do you register OCX/VCL for hobby proggs.?
Cactus datashield sold toc alteration (price???) because CD has a "open" ISO file format, understanding open like lets you play with it. I'm interested about DVD ISO file format because is more "closed" and like CCDLOCK idea you can make the same prog.(CDS) but free.
So 2 ways to protect video DVDR:
a)Alter TOC like in CDR/Multisession tricks (I think it's impossible) any idea?...
b)Autorun hidden prog. (not very accepted but works)
BR and happy new year
