I haven't installed my Mod-chip yet because I have some questions before I do so. I bought a PS2 version 1 I believe (not sure yet) off ebay and it will not read any of my back-up copied DVD movies, the movies are on TDK DVD-R media I get a Disc Read Error when trying to read them. Also I have a back-up copy of a ps2 game on some cheap-o media which I would assume it would give me a "Please insert Playstation or Playstation 2 format disc" but instead it gives me the disc read error. Another thing I should add is that it plays all my original games fine, loads them everything. So to get to my question here am I getting these errors because of the lens, or is it something to do with the bios and or firmware? Or could it be my media possibly? Another question I have is that if I install the mod-chip properly will it override these problems and magicaly work? or am I screwed and I just need a newer version PS2 off ebay and sell this one again? Thank You PS when i bought it, it had a Disc Read Error which i fixed, could this also be the cause of it?
