Learning on televised poker is trouble, as it's a different situation. You're either at a shot stacked final table (WPT) or all the boring stuff is edited out (HSP, WSOP, etc.) or people have to be exciting to get invited back (HSP & PAD) or there is some other gimmick going on.
The best way to learn is to educate yourself. There's a lot going on and so many things change depending on the situation. For example, sometimes you fold A/K pre-flop, and sometimes you call a shove with 6/4. It's all situational.
Reading Harrington on Hold'em is a great way to understand the various stages of the game, and the implications of chip levels and table image.
It's sort of like algebra. AB+C = D
You won't ever know the value of D without knowing the values of A, B, & C. If you know A, B, & C are all low numbers (a range of 1-10 for example) then it's best to know what A & B are as they have a greater potential impact on D, but still you need to have a fairly good idea of each factor to understand what D can be.
My point is, just watching other people without cards revealed, it'd harder to figure out what's going on. And if you're watching freerolls (where play is bad) you might even come to wrong conclusions.
That is, winning the hand doesn't mean it was a good play in the long run, so you shouldn't necessarily make the make that same move just because you saw it win somewhere else, in another situation.
