CGTalk - Animation: Loop

I am not getting a handle on this 'simple' problem...

My animation, which results in an infinite 30 frame loop like a bouncing ball or walk cycle, does not run 'seamless'. I can't get the frame 0 and the last frame to 'sync' up velocity wise. In XSI I press a button 'LOOP' and SNAPPPPP the first and last frame are aligned with their tangents. No stutter, jump, missalignment. To make matters worse... I find myself unable to produce the same velocity 'from' the first keyframe or to the 'last' one. I tweak like mad but it just doesn't care about it's left or right handles in the first or last key.

Is there a simple way to have the first and last frame act like any other key in the timeline?
I feel so mega awkward...

Sighhhh

Also, which version of C4D are you working in?

Details depend on whether you're using r9 or r10. Generally I find the easiest way to get a loop is to use the shift key when you move the playhead (Alt in r10) from the first frame to the last to ensure that you have the same key values. Then go to frame *before* the final frame and set a key. Then delete the key at the next frame. Now set your cycle based on the first frame and the new last frame.

I got it. Slept over it and the render fairy brought enlightenment. All in the noggin....
I had chosen the wrong phase for my start. I have shifted the intended curve and slected different frames for the 'zero' transitions and voila, no more interpolation problems. Dang, once you start on the wrong foot the curves really start fighting you. I started with 9.6 and after receiving the upgrade to 10 I am not looking back. 10 IS different, but soooo much better. Specially in that category.
Cheers and thanks for the ideas!
