I haven't done p90x but I do similar circuit training. Anything like p90x, insanity, and the like will give you the same results.
If you don't NEED to watch the video and can do the workout on your own with written instructions, you can save your self a lot of money by downloading the Tough Mudder boot camp program which is circuit training just like p90x. You just have to read the workout rubric and do it on your own but its FREE!
If you want it, just PM me and I can get you the link to download the pdf.
