I think that most of the weight workouts could be modified to suit you. I don't own a barbell, use a step stool to do step ups, and just lie on the ground on a workout mat for prone exercises like chest press. Every once in a while a DVD will do an incline move of some sort, but I just do a regular prone move instead.
My favorites are the Gym Style series, the Pyramids, Muscle Endurance and Muscle Max (sadly I lost this DVD so I haven't done it in a long, long time). All of those would have to be slightly modified, but I have no problems. I also like the CTX series and used to really like Maximum Intensity Strength (don't have this on DVD though), and those probably wouldn't have to be modified at all. I think that a lot of Cathe's oldest workouts are just plain weights - no high step, stability ball or band. So, you might look at Power Hour, the Slow and Heavy Series, Pure Strength, etc, etc.
