I agree with you, FF is not the best video camera!

APS-C so a better job!

Now, in terms of DOF, we need to consider than a smaller capture area gives you more (deeper) DOF. So your friend's camera, which is 'full frame' will naturally have a shallower DOF that your camera and the focal length difference isn't enough to make up for it.
There are advantages and disadvantages to this. For example, those who want a shallow DOF, it's easier to do with a full frame DSLR. On the other hand, if you need more DOF and are limited by light levels, you can get more DOF on a crop DSLR, in the same light. I know a pro wedding photographer who shoots with several cameras, including the 1Ds mkIII, 1D mkII, 40D, 20D etc. He likes the 40D for shooting at the ceremony because it's easier to get two people in focus while shooting at F2.8, than it is with the bigger sensor cameras.
