Hi Rubbish!
Ripped in 30 is a very similar format to Shred (timewise, but 1 more level than Shred). Level 1 is very easy but after that it's a step-up from Shred.
Killer Buns and Thighs is an excellent DVD - does what it says on the tin. It's a bit longer at 30 mins.
No More Trouble Zones - around 40 mins, all strength, no real cardio. I hate it because I find it really hard!
6W6P - around 40 mins again I think. 2 levels - it's a great DVD but take care if you have any back issues.
Extreme Shed & Shred - is really fun. 2 levels, 30 mins each. Takes a few goes to get into the swing of it but it's a goodie. Probably not as hard as some of the others, Level 1 anyway...
Burn Fat Boost Metabolism - 40 mins cardio all the way. You will feel nicely cooked by the end. Has circuits so you don't have to do all of them if you don't want to (same with No More Trouble Zones actually)
Yoga Meltdown - I am becoming a total bore about this one as I adore it. I think it's a fab DVD to mix in with some of her other workouts!
I'm sure there are more, but I can't think ....
My current favourites are Killer Buns, E Shed & Shred and Yoga Meltdown. I guess Yoga Meltdown might be a good option compared to the others with a bad ankle as there's no jarring impact as it were, I'm not sure though.
I'm not a Jillian Michaels nerd at all, oh no...
