I know copy right laws vary from nation to nation but here in the US it's not legal to make an archive of your DVD/Blu Ray collection. But it is legal to copy your CDs as long as you don't share them online. http://www.geekstogo.com/forum/topic/250669-copyright-laws-and-how-they-apply-to-geeks-to-go-policy/ I wish it was legal to archive of your DVD/Blu Ray collection as well, because imagine having a Raspberry Pi or some other small affordable computer and being able to play all of your DVDs & Blu Rays on one device no need to put them in your DVD/Blu Ray player it would all be in one place. And yes I know there streaming services out there but they don't have everything available like certain niche movies for example.
Anyway please share your thoughts.
