Just use the newest Raw2Dng.exe you can find, it worked for me at least.

I am currently thinking about making this something of an app you use on your notebook on set, so it copies, and optionally compresses your DNGs aswell.
What are some of the compression options out there?
I was thinking of some tests with Adobes DNG Converter. Ideally we could use some freeware for this aswell like 7-zip.
Other ideas?
7-zip gives about 50% on ultra and 80% on fastest compression setting.
I will also look at the lossy compression from Adobe.
EDIT: lossy compression is great, you seem to lose no detail, but filesize is greatly decreased. My first test gave a reduction to about 34% file size while remaining directly usable. this is great!
