There is a thread on here you should check out... search for "Best workout DVDs" (I think) and it has some great suggestions!!
You can always find new things OnDemand and Netflix if you have access to either of those.
Now hear me out... But I love there is a Carmen Electra DVD that I love. It's the one called "Fit to Strip" and there is nothing to do with striptease in it. But Michael Carson lays out a good workout in it that I love to do! I don't really like her other DVDs, but this one I held onto! You already mentioned my other fav... the 30 Day Shred!! (Gotta love Jillian!!)
