I contacted Acard support in the US and they acknowledged the download page wasn’t working; they had it back up within a day. I downloaded the latest firmware, which was just one version newer than what I had. Now I can burn five discs at once, the burns look uniform and they all verify.
Then, another problem. The controller display would get dim and it would reboot, stopping the burn process and ruining the discs. The power supply was holding okay so I replaced the power adapter cable (IDE to SATA), the display remained bright and the burning process went uninterrupted.
I think I have 100 hours in the authoring process and duplication process; most of the time was spent overcoming the frustrations of Adobe Encore 5.1 Perhaps I’ll have another project and everything will go smooth.
Thanks for your correspondence.
