Short answer: No.
Long answer: No.
You can spend a few thousand dollars to replicate the DVD with CSS, but that only stops the stupid. There's dozens of free programs on the web that bypass CSS to make the DVD contents copyable.
For a little more money (OK, a lot more) you can replicate the DVD as Blu-Ray disk. At this time there's only been one crack of the Blu-Ray and few people have the hardware or software knowledge to copy a Blu-Ray disk. But that's just a matter of time.
Either way, anyone can play a DVD and capture the component video.
I read elsewhere in the Forum and in the DVD-A Pro manual that the CopyGuard feature is intended for when you prepare a master which is then sent to a facility that presses DVDs. The CopyGuard doesn't protect the DVDs that we burn at home. However the pressed DVDs can be pirated by the various copying methods that Steve mentioned, so it doesn't really work there either. Is my understanding correct on this feature?
I haven't graduated to BluRay yet. Is it true that home-burned BluRays can be copied same as their DVD cousins? That was my take away from the other comments in this thread.
Home-burned Blu-Rays can be copied just as easily as home-burned DVDs and CDs.
Factory-pressed Blue-Rays can be copied just as easily as factory-pressed DVDs.
