You are clearly getting drive to both axles as you can just about make out the far side front wheel spinning. Now it does not say in your spec sheet but if you have quadratrac 2 then that behaviour is normal (you will send the drive to the tyre with least grip- not the greatest design but thats how it is!). If you have quadradrive then the quadradrive unit in your front diff is Donald Ducked (as we say over here in the UK!).
I have QT2 and find that a little left foot braking whist in a situation like that will help spread the drive more evenly accross both front tyres.
