First off, it doesn't mean that we can't play iTunes movies on all kinds of projectors. However, if you do get the HDCP error, it could be caused by the combination of the following two reasons.
1. Your projector may only support SD resolution. Many old models or cheap projectors don't support 720HD resolution let alone the 1080P FHD resolution.
2. You have downloaded HD iTunes videos from iTunes store which is subject to HDCP(High-bandwidth Content Protection). Technically this copy protection technology from iTunes will automatically check if the playback devices are HD compatible or not. When an incompatible device is detected, it will simply stop to display the encrypted video singles.
So what can you do in this situation? Here are the top 3 recommended solutions.
1. Buy and redownload the SD movies from iTunes store. Also, you can go to the iTunes preference window to choose the option to download SD M4V videos by default.
2. Upgrade your projector to a new one with 720P or 1080P resolution. With the development of electronics, most powerful HD projectors have become affordable for average users.
3. Get rid of the FairPlay copy protection from your HD videos movies so that to keep the best quality as well as play them on any devices freely.
