In addition, we may want to play the movie(s)/videos(s) on a device which doesn’t have a DVD/BD drive, such as a smartphone.
However, a large DVD/BD collection take up a large amount of physical space and constantly handling and playing with them can lead to damage, which can sometimes affect the actual playback of movies. Watching movies is a big part of several of our lives and thus many of us have accumulated quite a bit of DVDs and Blu-rays (BDs) over the years.
