problem burning ps2 cdr please help

[groovster]

i'm actually having a problem close to this. the machine is a v4 w/ a magic3.1. ps2 dvdr will boot fine, psx cdr will boot, all originals boot. ps2 cdr will begin loading, but won't quite get to the "playstation 2" logo, it reverts to the chooser screen, then throws me the red screen of death. if i boot to psx-cdr mode, the disc is recognized as a black bottom psx disc, but eventually chokes on loading the game. different medias, different games, and different software have been tested...could this be a problem with the mod and/or install?
