Do I rebuy the things I like/love after moving out?

So since I was raised by my father most things I like and pastimes are basically things he likes. I'm still debating whether or not to keeps with borrowing things every so often from his, or to actually buy my own physical copies of things he owns. For reference he has a film collection coming up to 1000 and a good 200 odd games spanning 12 consoles and probably about 200 CDs too. For as long as I can remember he's had an open door policy on anything he owns, and I've always simply popped into his room to grab something to watch or play. (Obviously I wasn't allowed to touch the 18s till I was older).

The things I'm considering buying for myself is things I've always had open access policy to in the past, such as Stargate SG-1, battle star Galactica both old and modern version, lord of the rings, Steven king movies, robin Williams movies, iron maiden, linkin park, Tina turner, queen, and a few more too.

For the cds I'm debating whether to buy some blanks and cases and rip them all or to simply buy my own copies. But for all the collections and box sets I'm not too sure on.
