Then I would suggest you don't follow a circuit training DVD and lift heavy, lower reps to muscle fatigue. You could do a full body routine in 20-30 mins. Do some HIIT for 20-30 mins on alternating days (or same day if you want more cardio).
Much more effective, much faster results.
But if you want to continue with your circuit training there's always Jillian Michaels. She has quite a few circuit training videos; 30 Day Shred, Ripped in 30, Killer Buns and Thighs, No More Trouble Zones, Shred it with Weights, 6 Weeks to a 6 Pack, etc.
I do one of her videos (and a short HIIT session) before my regular ST program for increased endurance, extra attention to smaller muscles, stability with the bonus calorie burn. I also find it warms me up to power lift and I can lift heavier after I loosen up from one her videos. However, that makes my workouts on my ST days up to 2 hours long. If I were pressed for time, I'd skip the circuit training and go straight to lifting with a little bit of HIIT.
