Sophiem,
If you haven't already purchased "KPC/Legs & Glutes" on DVD, here's a suggestion that you might want to consider: Buy it from Collage Video. They have a 30 days satisfaction guarantee, so if you decide that you don't like "Leg & Glutes" enough to add to your leg workout rotation, then you can return it for a full refund (minus shipping cost. If you do send it back, choose first class mailing---it's very cheap).
And if you decide it's a keeper, then Collage has a replacement guarantee on all of their DVDs. What's so nice about Collage Video is that they accept opened DVDs as returns, as long as it's within the 30 days time frame. I think it's a win-win situation. Besides, I think DVD quality is so much better than that of VHS and well worth the money spent.
I love my "KPC/Legs & Glutes" DVD---wonderful DVD options and the 2 workouts themselves are great!
