The development of streaming media really enables us to enjoy a wider range of film and television resources more intensively, but many platforms also need to be recharged, and the film and television works I want to watch will be distributed on different platforms, which means that I have to recharge the members of many film and television platforms, but if I save DVD to computer, I can play it at will, and I can only buy the DVD I want to watch, which will be more cost-effective and valuable for collection.
