• The Mac-Forums Community Guidelines (linked at the top of every forum) are very clear, we respect US law and court precedence when it comes to legality of activity.

    Therefore to clarify:
    • You may not discuss breaking DVD or BluRay encryption, copying, or "ripping" commercial, copy-protected DVDs.
    • This includes DVDs or BluRays you own. Even if you own the DVD or BluRay, it is still technically illegal under the DMCA to break the encryption. While some may argue otherwise, until the law is rewritten or the US Supreme Court strikes it down, we will adhere to the current intent of the law.
    • You may discuss ripping or copying unprotected movies or homemade DVDs.
    • You may discuss ripping or copying tools in the context that they are used for legal purposes as outlined in this post.

I have an Optoma projector connected to a Macbook Pro with Retina display. It will show Powerpoint presentations made on the Macbook, but will not show a video movie showing on the Retina display through the projector. Is there a setting I need to adjust?

Have not tried it on any of the newer Macs, but the Macs I have will not show a video on both screens at the same time (in most apps - no apps I have tried).

You could do this by either using the projector in extended desktop mode and dragging the video to that screen or possibly in mirrored mode by making it the primary display

For explanation of the two modes see Post # 2 Item # 3 here.
