Thanks for the clarification, I have updated the gallery section of my page with the video and translation.
Regardless of what the problem was, the Volvo should not be labelled as an AWD vehicle if it can't make it up that silly little hill.
When I got stuck I was really cursing the open diffs. You could tell that they AWD system was having a hard time with my situation. Only 1 wheel was touching the ground, it it of course, got no power. I really want a rear LSD, although that wouldn't have helped me here.
It was pretty much driver error and bad tires that landed me there. What happened was that I was scraping the front bumper too much going up and so I backed down slightly to take a different line and the side of the hill broke off and slid down into a little marshy area, leaving 2 of my tires in the air when the car slid backwards onto a stump/rock/whatever.
