Hi!
You did not mention what type of cardio workouts you do and for how many minutes.
I started seeing superb results with my body fat loss only after I increased my cardio to 5 days - all high intensity.
I do 2x Cathe's BodyMax Step Only (without the step but my jumps are really high) And 3 days with non-Cathe tapes but high intensity workouts (Aero-box, Kickboxing, sports cardio etc.,)
I also do weights. MIS and PH are my favourite 2 endurance workouts. I do a workout twice per week but not in the same week.
I own S&H DVD but found that I could not fit in 5 days of cardio every time I did S&H workout. Plus I gained muscle that made my arms look bulky not toned, although they were getting toned. So I decided to get lean first. This mean stick to a strick 5 day cardio workout week. If I can't fit in weights then that is fine. For now, even 1 total body day was better than none.
I have shelved S&H for now until I get down to my desired dress size. I love the workouts but I want to concentrate on getting down to my desired size first.
I have checked out a lot of cardio video previews because I was looking to buy some new tapes. From Cathe's catalog I thought Rhythmic step+ which comes with an Interval workout and MIC is a great DVD to have. The workouts look intense yet fun. Also, 10-10-10 - I have been eyeing this one for a long time, I just can't afford it right now cause it costs $32 Cdn (ouch!) shipping + taxes not included!
Non-Cathe cardio workouts - you might want to check out the videos on collagevideo.com before buying but I have "Slammin' Sports Cardio" by Mindy Mylrea (this is my new buy and I love it!). Aero-Box by Kathy Smith and Michael Olajedi and of course Tae-Bo, Kickboxing with Kathy Smith and Keith Cooke. Some people here also recommended PowerStrike kickboxing series. It's on my wish list and plan to purchase it as soon as it goes on sale.
Cheerio!
