It's sort of like the situation with blue tooth Sony earbuds or wired earbuds. The wired traditional earbuds retain the full bandwidth and range of music while there is a drop off with blue tooth buds because sound waves are digitally compacted. A trained ear can tell the difference. That's why I'm asking. Streaming movies entails a drop off in audio and visual detail. A copied Blu Ray movie won't have the detail that a trained eye and ear can discern. Correct me if I am wrong. I'm an old timer and I've been away from the States for a long time. I used to buy Blu Ray movies that were clearly sealed and you could tell that they were direct from the studios and producers. What happened while I was away?
