Query: One of All-Time Best Aerobics Routines

I have about 30 exercise tapes (and most of her aerobics tapes) so I should know. Even though it looks dated now, this is a great interval workout. One of the few aerobics tapes to actually be long enough to do some good (many are 15 min, few over 30). I have used this video for almost 10 years. You can follow the too perky but high impact woman or Jane, who is kind of medium impact, or the low-impact woman (she is great!). There is also a guy who comes in and does a 20 min version during the whole thing, so there is something in it for all levels.I hope this comes out in DVD soon, I skip around a lot, combine it with other tapes...and it would be great to have the random access of a DVD. Not to mention, my tape will die at some point...
