Yes, going down to the appropriate depth does require some hamstring flexibility, but the hips are the typical culprit. Your hamstrings will most likely feel a stretch if you are sitting back properly. If you need to start with a high box and lower it gradually, do so. The rocking you see on the videos is most likely:
a) the guy is actually rocking
or
b) the person is leading with his head and thrusting his hips forward, which can deceitfully look like a rocking motion on video footage.
Just make sure to briefly relax the hip flexors and to lead with the head and spread the floor.

Thanks. It feels weird right now. I haven’t tried the move with any weight yet.
Thanks for the info. Maybe I am going too low at this point. I tried to initiate the upward movement with my head and I still feel like I am rocking up.
I will try the movement without going so low and see what happens. Thanks again.
If you think that it is rocking that you see it is probably the leading with the head, push the knees out and spread the floor action that was mention. Please dont push down with your feet, you gotta spread the floor!

barbender242,
Thanks. I tried to emphasize pushing the knees out and spreading the floor like you said and it felt a lot better.
I am still trying these without a bar at this point, so things may change when I add weight.
