Looking for some movies from the 80's or maybe 70's in the Sci-Fi category I guess.

Hi guys. Hope it's okay to ask and, someone can help identify these.

Or if you know a forum where a lot of movie geeks gather, that is also helpful.

Have been trying to remember some movies I watched as a kid back in the 80's.

1. All I remember of the movie (or was it a tv series?) is a scene where a father and son playing basketball outside with some other people. Father telling the son to be careful not to jump to high. As they where originally from one of the biggest planets in our solar system and being used to higher gravity made them able to jump higher than normal humans.
   
   
2. From this one all I remember is people on a spaceship(?) eating breakfast or something, maybe just woken from coldsleep (or whatever it's called), one person goes to the garbage disposal machine/chute. Checks the logs, or at least sees that a human has been disposed in the machine. And they then find out one of them has been replaced by an android I think.
   I was thinking for a long time it was one of the Alien movies, but it does not fit those.
   
   

I do not remember if these was on rental movies here in Norway at that time, or if it was shown on either the Premiere (Prem1ere?) or Sky Channel tv stations
