I have found Digital Photo Professional to be the best RAW converter. Stick with it. First copy from you microdrive to an empty folder on your C: drive. Open DPP, select your folder, select the RAW files, and use the batch process command to convert them to tiffs.
This is very interesting.
I am using DPP as my main convertor - I love the interface. I hope to have CS2/ACR shortly.
Some seem to complane about DPP's rendition of red (poor colour graduation). What I have noticed is that the red channel saturates easier on DPP compared to EOSV, the only other RAW software I have at present. The Blues and Yellows on DPP I have found can be recovered much better from overexposure than EOSV.
Can you expand a bit more about what you like about DPP and what you have compared it to.
I have the feeling DPP gets an undeserved bad press.
