I will leave the motorized system response to the more experienced members and mods. But there are a lot of threads and posts regarding this for self help read.

Regarding the XXX, please read this thread:
Adult Channels Quality on Hot Bird
My recommendation is to buy a smartcard which is 24/7 and with the best bitrate so that you will always have something on to watch and if you get anything else then consider it as a bonus.
For films, I would recommend to buy Canal Sat (France) on Astra 19.2E smartcard (nice price at the moment from a certain website).
Sports? I gather that DigitALB is quite popular.
