HRMS, Calories burned, IMAX

I want to first start off by saying I have lurked forever and love this forum. I found Cathe on FitTV after doing the Firm for two years. I thought I was in good shape with the Firm... but oh my, Cathe still leaves me exhauseted (in a good way) at the end of her workouts. Needless to say, now when I want an "easy" day, I don't reach for Cathe, I reach for the Firm.

Now for my question, I just finished IMAX- from the Intensity Series. Like I said, I used to work out with the Firm, and would burn about 600 calories for a 60 minute cardio workout. I wear a HRM, but my battery is going dead. This Imax was 55 minutes, and my HRM said I burned 850 calories! Is this possible, or is the low battery affecting my readout? When I glanced at my watch, I worked between 70 and 95% of my heartrate. I had to pause the video three times to take breathes and help my kids with some issues... but that seemed really high. I just don't want to overestimate my calories burned. Thanks for your help!
 
It's hard to say without knowing your age, weight, etc...but I'm 27, 160 lbs and 5'9 and I burn about 700 when i do IMAX 3, about 650 for IMAX 2
