identify who actually makes ur DVD-R media

[patch god]

maybe ur writer burns light dyes better than dark dyes such as ritek. i doubt its ur ps2. they will read ANYthing that is burned with low amount of errors, jitter, high reflectiveness etc.

do u have a liteon dvdwriter or dvdrom? u can do some error testing if u do? just say so and i'll link u to a program u can download that will scan the error rates on ur burns. its excellent to compare different media at diferent speeds etc.
