Problem with multi-session recording

Hi guys,

After using Roxio software for ages, I decided to try Nero. I downloaded its ultra-edition (ver. 6.0.23) and tried to burn the multi-session disc. But all I received is the following message - “This disc cannot be written in track-at-once” and was proposed to use DAO and finalize the disc. Two problems:

  1. What is wrong? Nero InfoTool clearly identifies my drive as TAO enabled. I use branded CDR discs.
  2. How is that I could not find the explanation for the above error message anywhere in the Nero documentation?
    Thanks in advance.
