Strength DVDs that are easy on the Knees?

What are some of your favorite workout DVDs that tone your body without jumping or other moves that are hard on the knees? I get plenty of cardio already on my treadmill so I'm not really concerned about that, but I'm bad about skipping my resistance training (because I don't like it and don't have a lot of creativity for mixing up a routine) and was looking for some good videos I could follow at home that won't be too hard on my joints (I'm 6 months pregnant and jumping and moves rough on the joints just aren't good right now).
