I should have been a little more specific, I am not in anyway unhappy with the results I get with ACR. And, I do not use the default settings in either converter. I do adjust for each image, or for each set of images separately. There is an undescribable quality that I see in my DPP conversions that I do not see in my ACR conversions. I suspect that when I finally upgrade to CS5 (or the current version when I do upgrade) that the newer ACR version will probably be an improvement and I will return to using ACR. But, I need to replace my 2.4 ghz 2gb memory Windows XP machine first. I imagine that CS5 will be a little to much for my poor computer. So, DPP is my app of choice at the moment, and I am trying to integrate it as best as possible into my editing workflow. Thanks for your response.
