1. According to the dms3 forum people have there share of problems with this chip. V4 consoles had weak lasers to start with. if its has ANY problems reading dvd media then i would sell it and buy a new console.2. Team DMS claims it works but i know no one with a dms and hd to confirm it.3.Matrix Infinity, which is my personal choice over the DMS3.I ordered my chips from
www.divineo.com. there about 50 bucks and worth every penny.
