Dxo Optics Pro 11 essencials edition is free until November 11th: http://www.dxo.com/us/practicalphotography
I downloaded it and played around with it for a couple minutes and it's pretty nice! Seems far faster than Lightroom, very far. It's free so it's worth downloading just to try!
I downloaded and installed this program. It can read DNG Converter files (CR2->DNG) from my 80D/6D. It can make DNG files from my 80D/6D raws. It CANNOT see the DNG files that it creates. Odd.
EDIT, Screen shots:
First shows Optics Pro folder open. Note 9 files.
Second is same folder, in Explorer, showing DNG files that Optics Pro created, but cannot see.
