Query: Would be good if all 4 workouts were on the DVD!

I got started on week 1 and really liked the workout. I'm in pretty good shape, but I worked hard to finish it and was even a bit sore the next day in my glutes and hamstrings (yay!). I was also motivated to keep doing the workout and move through the weeks. Really good for a short workout. Jillian is a nice mix of tough, funny, inspirational, and high energy. If you want a sweet girl coaxing you into working out, this ain't for you. If you want someone cool to push you through a short but intense workout, she's your woman. I watched week 2 and it looked good too.BUT, when I tried to preview week 3 and 4, there was nothing to watch. Apparently no one put those files on this particular DVD. So now I have to deal with contacting the manufacturer or trying to make Amazon help me, or whatever. Or just giving up. It's impossible to communicate with anyone, it seems. Really disappointed with quality control.
