Newbie needs tips on correct media

[deerayrose]

I will be purchasing a dvd burner and media within the next few days. (win xp system) My most important needs will be backing up PS2 games, and DVD movies. I have some idea of what I need, however I'd like to ask a few things straightforward to assure I don't totally screw things up.
(yes, the ps2 mod chip is already on the way(v 10 ps2))
My questions are:
1. For my needs, is DVD-R (rw) better than DVD+R (rw)

2. Are Dual format (- +) drives ok for burning the correct type media for my needs?

3. Are General Use dvd'r's any good for my needs?

4. If there are any tips and suggestions anyone can give me to get started please do, such as the best software to use, best media to use, ect.

Thank you!
