iTunes has copy protection on their movies called HDCP which will not allow you to play iTunes rentals or purchases on some older data projectors. Thankfully there is a simple solution. You just need to watch an SD version of the movie and it does not have the HDCP protection. This is not mentioned on Apple’s support webpage but I was able to find out about it when I rang Apple iTunes support. Read on for how to do this step-by-step.
I recently tried watching a Netflix movie on a data projector and it would not work. I have subscribed to Netflix, but my data projector is old and Netflix have a copy protection on their service that won’t let you play to older data projectors. Thankfully there is a way around this. You just need to set your web browser to an older version, and it will use an older piece of technology to play the movie which will work on an old data projector.
