Hi, i try to burn an iSO make with PGCedit followed step by step, and IMGburn give an error for writing media. It gives error "Interpretation: Cannont Write Medium - Incompatible Format". I was trying to burn on a Ridata DVD-R DL 8.5GB with my latest NEC ND3550 V1.5 the latest firmware available on Nec Firmware update. What does this mean? With Nero, burning Image give another king of error "Cannot Burn At Once an Dual Layer". All programs reconize that DVD-R DL. Help me with this please...
