From my past run ins with this.

We use a region free or "world player" and avoid copy protected links like HDMI. I found it surprising to find Amazon.com to have such things now. I bet Amazon.ca has them too.

I can't guess why it worked before but it's a well discussed topic and as you discovered the big name makers must "OBEY" the regions and more. I hope you can figure that much out.
