Prodisc MCC 01RG20 and pstwo

anyone had any luck with this dvd and slim pstwo I’m using the Nec 3520a with 1.u6 firmware and I burned like 8+ games with it none of them worked right, burning these 4x prodisc MCC 01RG20 at 8x, works but audio skips or stops completely and sometiimes the game freezes, 6x, 4x, 2x , 1x almost never works just freezes…

get liteon as reader and nec as writer.

4x read speed, 4x write speed

What brand are these disc’s ?
