Help out a Confused Newbie

[Bustacap2K1]

hey, I'm very confused now..
I have a DVD reader and burner (the Pioneer A03 or something), PrimoDVD, some blank DVD-R's and DVD-RW's. I also have a modded PS2 with a NEO2.2 from www.mod-chip.com. (I have a GS2 v. 1.91 and a GS2 v. 1.2.1) i've backed up normal PS2 games and played them fine before but now I notice that all the new (good) games have silver bottoms which I have picked up that are DVD's. Using a tutorial from psxcopyworld on burning a DVD with PrimoDVD, i copied Dynasty Warriors 3 (not EA [DVD]) to test it. it copied successfully but I cant get it to play. I've been hearing also about something of the TOC (which I think is Table of Contents) being bigger as an original or something. So if you could help me out, here are my questions:

1. Can I play a DVD game on a modded (neo2.2) Ps2?

2. Is there anything in the tutorial I may have missed that made the game copy incorrectly (the sizes of the original and the backup are identical)

3. Does Dynasty Warriors 3 have some sort of protection against it or something?

4. What's that about the "toc" and what do I have to do about it?

5. What should I do to boot the DVD-R? (keeping in mind my GS2 versions and Neo2.2 chip)

6. If #5's boot method is a long one, are there any shortcuts?

Thank you for your time.
