I've burned 3 different downloaded games( All pal or regoin free) 3 times each on verbatim DVD+R DL discs using a PIONEER DVDRW DVR-K16 burner with clone cd. But all I get is unrecognised disc when attempting to boot. Thats 9 out of my 10 discs useless as coasters. I've only 1 left. Where am i going wrong? (flashed with Ixtereme firmware from local shop gametex) The helps much appreciated guys!
