Hmmmm... squats definitely have the travelling knees.
Can you get your bum further back? I can't really see from the angle, but combining that with pushing your knees out to the right angle at the top is something I've been working on to get my glutes more involved in the squat.
Regarding the deadlift, LiE's suggestion rings true - there seems to be a lot of 'pull' on the bar during the first half of the lift.
Nice weights, however - kicking my posterior with over 20kgs more mass (not necessarily muscle, of course)!
