Eddy -
I had just received my new RD1s from the nice folks at Robert White Friday morning. As I was waiting for the battery to charge, I noticed your post about the Adobe apps not opening the RD1s' raw files. This gave me a bit of panic.
I'm running two Macs (a G4 powerbook - os 10.4.9 & a G4 tower -os 10.3.9). While waiting for the battery to charge, I down loaded the latest version of the Camera Raw plugin and the Adobe DNG Converter, (The Mac version of both the Camera Raw plugin and DNG Converter is 3.4 (89) and has the created date of 28 April 2006. I installed this onto my powerbook, and all things were sweet as it recognized the RD1s files.
When I tried to open the raw files on my G4 tower on Saturday, the Bridge app and Photoshop CS2 would not recognize them, and reported a parsing error. I then quit both apps and downloaded the above mentioned files. My desktop machine now opens the RD1s raw files as it should.
I hope this info helps you.
Take care,
Michael
