The 1610a does not support "overburn" and therefore cannot exceed the indicated capacity - even though THIS media is designed to!
If this has been rectified in later firmware (test using the "Overburn test" in the Nero CDSpeed (in Nero Toolkit), then you will need to set up Nero to allow overburning to 89:59
Easy Cd Creator will NOT support >80 min operation, as they do not allow overburning.
