I have started my own DIY telecine project about 5 years ago. When searching the internet, it was very obvious that Roger with his Workprinters has developed a unique sytem. The modified Gaf projector, the special bulb, the condenser lens, the modified mouse and the Dodcap (later Cinecap) software. I do not know of any other systems like this in those days. Later, the Tobin unit was there too, but this is a complete different design.
It was also very obvious that Dodcap was made for the Workprinter and that Jeff and Roger where working very close together on this. It's their project and they are free to do whatever they want to do with it.
I have understood there is no patent on the Workprinter, so anybody can copy it and sell it. Personal I would never do this, because I do not like the idea of copying ideas from others. Fortunately, I have enough ideas of my own.
Now, if someone wants to build a Workprinter clone with the intention to sell lots of them, then please make your own software or make a good business deal with someone else and never refer to any software without asking the author first.
About the price of quality telecine units: it is not possible to get a top quality product for an insane low price. If you do not have enough money then build your own unit or get yourself another hobby. (or work harder

)
Fred.
Ps: my own units are no Workprinter clones, I do not need Cinecap any more and I do not sell them.
