I've read some, but I still have a couple questions: 1)Is the Matrix the best chip? I'm down for no soldering, but not if it means disc swapping or dvdr incompatibility. I also don't want games to detect the chip (i've read that MS stepped up security and newer games won't load on a modded Xbox. 2)can the Xbox read both DVD-R and DVD+R? Or is that dependent upon the mod chip you use?
