Ripped ISO from DVD, usable with Megui?

[20/20]

I know DVD-content is encrypted on it's original disc.
And I have a question about this.

If I rip the DVD-contents with DVDDecrypter my Harddrive (1:1 ISo frmat)
Will this ISO-rip have the encrypted video blocks just as it was on DVD?

IE. Can I mount this ISO-file > Use DGIndex to create a D2V file >
and after that directly encode contents using Megui from this mounted source with
No problem?

Or will I get "undecoded" artifacts in in the final movie??

Delete this thread please.
An ISO-rip doesnt suffer from a DVD-protection like the original Disc.
