I thought j2k encoding speed was more or less independent from content complexity. At
least I wouldn't expect a 1:4 speed difference between 'simple' and
'normal' content. But will do more testing while doing this project.

Is the J2k compression speed depending on content complexity or target datarate?
Yes, to some extent. Simple frames (with large areas of a single colour, I think) will
encode more quickly. Is DVD-o-matic maxing out your CPU successfully?
