I don't know about a DVD on the K10D but I read the book Pentax K10D - Magic Lantern Guide
, by Peter K. Burian and I wrote a review: see http://www.cameralabs.com/forum/viewtopic.php?p=6865#6865
I really appreciated the book and the advice provided: What to do in given circumstances? What are the photographic consequences of a specific setting?
The B&W pictures were not a problem for me, since they were an invitation to test by myself!
