Question on Insanity?

I hate to bring up repetitive posts, but I do have a question about the Insanity workout and how it works with other work out programs. I am doing some weight training 3x per week, and some of the insanity videos are over an hour long, so I would not be able to do both workouts that day.

I do not want to not do my weight training, even though I am a noob and probably not benefiting from it much at all. So for those that have done insanity, would I be able to skip it on the days I do my weights so that I am actually stretching the program out longer than the 60 days? I mean obviously I can, but the main question is will doing both cause me to hurt myself or something?
