Ok the issue here is the same content and same media fail in Roxio land where they succeed with Disk Utility. We have received this type of error in both popcorn and toast. Unfortunately, I neglected to screen cap the popcorn one.
After selecting ‘OK’ as noted above I received the following error.
If I take the same source and convert it to a disk image first using DU and then burn the DMG to a new disk it works 100% of the time with the same blank DVD media. I have confirmed that the drive of course supports the destination media.
In addition we own the copyright to the material, and need to send it out to affiliates, so it is not a copy protection issue, just in case you were wondering.
I do not have access to the machine at this time, as the user has left the country on holiday. I have given her several DVD-R discs from two different manufacturers to determine if your product just does not like the DVD+R media that they have been using. The odd part with that is that they made it half way through two different manufacturers cake boxes of the media before this started happening.
I have recently completely AppDeleted both applications and reinstalled both complete with the latest updates.
