scházet se/sejít se = go on a meeting with someone, you were told the date before (like you call your friend to ask him if he wants to see you, then you agree on where and when) setkávat se/setkat se = a general word for to meet seznamovat se/seznámit se = to meet a person for the first time and get knowing him/her potkávat se/potkávat se = accidentally (more or less) meet someone - like you meet XY in the kitchen být spokojený s = to be satisfied with (I like my new car, I'm satisfied with it) spokojovat se/spokojit se = to not be satisfied with, but you will (or will have to) get on with it (the car is not good, but you have no money, so you'll have to have it) The first word is infinite form - the continuing action, the process is more important. The second word is finite - it happens once. I hope it helps :)
