NeroVision fails to transcode files for video DVD


the Nerovision API only create video DVD video with files already compressed in MPEG-2, it fails for other formats at the transcode stage.
“NeroVision API Example” displays “error getting time” and creates an empty DVD.
My application catches a ‘DVD Engine error’ using GetLastError.

EstimateCreateNeroBurnContextTime returns false.
The IProgressCallback::OnProgress is called with an action == -1 at the beginning of the time estimation.

It works fine with VCD and S-VCD.
