Which Mod for DVD-R

[PS2 Newbie]

I'm about to but a complete system from stem to stern and need some advice. It looks like the No solder mod is the easiest choice but I want to be sure on compatibility. Will be buying brand new PS2, looking at the Pioneer AO4 burner, and (http://www.modchipinc.com/pages/nosolder.htm) this chip. I am experienced with all aspects of PS1, but have never done PS2. Have DVD to Divx experience as well. I would rather burn the entire DVD without downsampling. I read somewhere about dual layer DVDs and inability to copy. Any advice would be helpful... I have done a lot of reading, but this appears to be a moderately new chip and it looks like a lot of folks are downsampling to write to CDR vs. the DVDs. Media consideration helpful as well... will the low budget discs work?

Many questions in my first post... any help appreciated.
