Hey guys, I've been reading though several threads seeing if anyone else has ever gotten the same error I have... with no luck. One person had the error, but no solution was formed.

Here's my problem: I created a multisession DVD-R (The media is fine, this is my 6th disc that has burned fine at 4x) of program backups, etc. I can't access the data for some reason, so I won't to finalize it so hopefully I can.

When I continue a multisession in Nero 6 and check "finalize" it gives me the following error:

"PIONEER DVD-RW DVR-107D / Illegal mode for this track / PIONEER ... / Could not perform start of Disc-at-once / Simulation failed..."

It won't let me uncheck disc-at-once in the properties... I've got the newest firmware for my drive (1.15) and have tried finalizing without adding any new files and with adding new files.

Any ideas would be greatly appreciated. Thanks a lot!
