Hi Telesto,
First thank you for going to the trouble to create this plug-in and making it available to people!
I installed it and successfully loaded in several of my Canon EOS 30D CR2 RAW images using your plug-in and then Saved As a BMP with no problem. I confirmed the BMP save by opening the BMP in another app. It works fine!
It is slower than the Canon RAW viewer/editor, which is not surprising, I guess. It loads a CR2 file and displays it in its proprietary viewer/editor in about 1 second, whereas Paint.NET using your plug-in does it in about 8 seconds (timed using my stop watch).
