So, it would be bad in your eyes if I had an Amiga driver for PhotoCD. I tend to go with the other side of the argument but that's not what I'm asking. (I totally disagree with the idea of patenting data formats. Its one of those no win scenarios.) What I want to know is, what's the difference between me decoding and proccessing a PhotoCD image on my Amiga, and me decoding a PhotCD image on my PC then transfering it to the Amiga for processing? Also, don't you think it's a bit illegal for Kodak to withhold PhotoCD from the Amiga? It seems to me that there are some antitrust laws involved here.
