Also, FitTV edits many of the workouts, so you don't get the whole workout. On PLB alone, the warm-up is cut out (!!) and there is a very jumpy cut between squats and deadlifts (I think: I had FitTV on in the background one day, and PLB is on).
The one thing that I like about Fit TV is that you can at least try something out before you purchase. Just know that there's more "good stuff" waiting for you on the DVD! I learned that with my first purchase of BC +ME. I think they cut out the hardest part which I believe was called The Terminator! OMG!!!! The first time I did the DVD, I was like where did that come from that wasn't what I Tivo'd!!!
I do like all the premixes, bonus mix (I think that's what it's called), and that the DVD has chapters so you can pick and choose. Ideally, you could create a new work out every time you worked out.
