Click change - if you can do a Cardini snap change then it'll only take you a bit of practice to transfer the move to your other hand (left).
I've just literally got the change down after about a week of practice.
Tivo 2.0 - The more you do it, the easier it will get. At first i struggled a lot and abandoned the whole thing altogether but now can do it with ease. Will take a LOT of practice to make it look perfect.
Hope that helps and don't be afraid to put in the practice because it's worth it. When practicing other stuff, do TiVo and Click a couple of times and return back to your normal routines. I find this helped a lot.
