I would love to do that, since I also have a Nook Color, but unfortunately I do not know enough about the many options in the profiles to adjust more than 20% of them and I have not found a good source to find the information quickly. It is a very complex program and trial and error just isn't feasable
without a lot of information.
I think I read there was a new profile onverter in the works, but I am not sure. I believe they asked for patience as they are doing a lot there. Hopefully there will be a guide or Wiki to explain the various options and which conflict with others.
In any case I would use a short trailer from a to test various options and fins the best settings the quickest.
