Honestly.......wear a heart rate monitor.....or even a bodybugg/fitbit. That is the only way you are going to get a reasonably close estimation.

Insanity burn can be approximated quite well using a heart rate monitor.

The strength training portions of P90X are (supposedly) not estimated as accurately by heart rate monitors. P90X was design to burn an average of 600 calories per workout, so that would be a very rough guideline. www.p90xcalories.com is a decent approximate, too.

Personally, I take my HRM readout for P90X strength training and eat back about half of what it tells me.

I pick out something from the cardio menu and enter the amount of time that I worked out. You can find 'weight training" under cardio to figure out the burn for that. Today I wore a heart rate monitor which told me the amount of calories that I burned, so I entered it in cardio-aerobics (high intensity) with a time that gave me the correct amount of calories burned.
