I've been burning ISOs with DVD Decrypter for some time now, and am halfway through a stack of Maxell DVD-Rs (meaning that so far half have worked for me), when all of a sudden my computer won't let me burn ISOs. I burned one, went to try another...and now it won't work. No changes as far as I can tell, it just suddenly stopped working. I've tried several different DVD's, tried burning with Sonic (same error), and tried recreating the ISOs (all of which work fine when played via Daemon tools). The error DVD Decrypter is giving me is: I/O Error: Device: [0:1:0]_NEC DVD+-RW ND-3530A 102B (e (ATA) ScsiStatus: 0x02 Interpretation: Check Condition CDB 53 00 00 00 00 00 22 E1 3A 00 Interpretation: Reserve Track - Sectors: 2,285,882 Sense Area: 70 00 05 00 00 00 00 0A 00 00 00 00 30 05 00 00 00 00 Interpreation: Cannot Write Medium - Incompatible Format and the log is as follows: I 21:02:33 DVD Decrypter Version 220.127.116.11 started!

I checked for a firmware update via DVD Decrypter but it couldn't find it on the site, and tried with Windows which said about the same. Please let me know if there's any more information that would be helpful and thanks in advance for any suggestions!
