Ok, I've been burning CD's and DVD's with Nero 22.214.171.124 (and previous versions) for sometime now.. no problems whatsoever. All of the sudden, Nero acts extremely flaky with my NEC 2510a DVDRW drive. So I try burning a CD with my CD-RW drive and it works fine.. try with my NEC and no go.. I get a "Invalid block address" error. Now, with DVDs I receive no error.. the drive just appears to shut off and Nero just continues to act like it is burning. So.. I decided to yank out Nero completely and run the cleaning tools from their site.. reinstall, using the version on the disc and same issue. Try updating. Same issue. So by this point I've given up, so I decide to get a new DVD Burner. I still have the same exact issue. Anyone have an idea? DVDDecrypter burns a disc fine on the NEC 2510A.. so I'm pretty sure it's a Nero issue.. but I can't seem to isolate it.
