My PS2 wont boot dvd-r's

[scamper]

first of all if you can get a new ps2 with a a straight boot chip that would be the better solution but with the machine u have u will not be able to boot dvd-r's with that version of ar u need v1.90 or v1.93 also remember that the toc of orig must be higher than the dvd-r gta 3 is ok but i have had some probs now and again now i use devil may cry demo (also orig is good as it is the same toc) and had no probs at all hope any of this helps scamper
