I just installed a Matrix Infinity into my second PS2. It plays backup DVD-R's fine. But, it will not play back-up CD-R's. It says "Disk Read Error". These same disks work in the first PS2 I put a chip in. Also, when trying to play a PAL DVD-R, it says "TV system doesn't match". I have no idea what the problem is. Any help would be GREATLY appreciated.
