There aren't any copyright issues if you do it ONLY for youself and don't try to profit from it, or pas it around... It' the same as music... If you want to make a copy of something you already bought and use it for your own entertainment, there's no law against that...
Besides, I make copies of parts all the time, figures and engines and the like, and have yet to see "Copyright Police" kick m' door down...
It's like back in the day of LPs and casette tapes... I made tape-copies of all my albums to play in the car...
