I am not completely sure - isn't DVD not fully 1080p compliant but 720p instead - so there should be no down-conversion, right? The only DVD that I personally know of that has extra security are Lucasfilms like Star Wars, but I have not tried copying those yet (my old DVD player will not even play them because of their extra security layers).
EDIT: I just saw Zorg's post, so as along as it is not being upconverted, there should be no issues, right?
I am not sure what you mean by complaint here, but DVD resolution are (taken from Wiki)
* PAL:
720 × 576 pixels MPEG-2 (Called full D1)
704 × 576 pixels MPEG-2
352 × 576 pixels MPEG-2 (Called Half-D1, same as the China Video Disc standard)
352 × 288 pixels MPEG-2
352 × 288 pixels MPEG-1 (Same as the VCD Standard)
* NTSC:
720 × 480 pixels MPEG-2 (Called full D1)
704 × 480 pixels MPEG-2
352 × 480 pixels MPEG-2 (Called Half-D1, same as the China Video Disc standard)
352 × 240 pixels MPEG-2
352 × 240 pixels MPEG-1 (Same as the VCD Standard)
As you can see, there is no 720p resolution here. 720p is EDTV, not SDTV.
DVD is 480p max unless you have a player that does up-conversion. HD-DVD and BluRay plays at 1080p or 1080i.
David Marsh - Lead Program Manager for Video has recently responded to the article by Peter Gutman and has confirmed that Vista will not allow you to play HD content at full resolution.
This is a direct quote from David Marsh:
" In the case of HD optical media formats such as HD-DVD and Blu-Ray, the constraint requirement is 520K pixels per frame (i.e., roughly 960x540), which is still higher than the native resolution of content distributed in the DVD-Video format."
The design specifications for HD is that it will output at 1080. So MS has decided along with Hollywood that your hardware will not output the proper resolution even if you have a certified HDCP monitor that you paid big bucks for the ability to view HD on your personnel Computer.
Please read Peter Gutman's response to David Marsh's 20 questons(scroll down to Microsoft's Response):

and another great rebuttal to the blatant lies that David Marsh used in his 20 questions article:

So please explain how MS is not using DRM to completely change the design specifications of your computer and hardware.
Let me leave you with this from a MS employee blog about exactly what MS has planned to do with DRM. I copied this directly off his blog:
To the poster above who said MS caved into Media industry desires, wrong, the desires of the media industry are cover for MS's *own* desire to control your computer.
With control of your computer (X-box is where we are headed) MS has no more competition on the platform *at all*.
Even more importantly they begin to eliminate the *possibility* of competition on the hardware platform.
It is GNU/Linux they fear taking what they have (OS and Office revenue streams), and Apple and Google taking the revenue they want (media delivery and the web services delivery platform).
To all those that are shocked and outraged that MS could so lightly consider them, MS has given a great deal of thought to you, just not about what you want. They are figuring out how to charge and market you.
And the greater the control of the platform the greater the opportunity to "maximize revenue", your bank account is the "revenue".
Free and Open Source software is the last real competitor they face, since they can't stop it's growth they will try to poison the ground.
For any who want to leave to their descendants a digital world where they are software owners rather than software renters, the choice is clear
