Apple has released a QuickTime update which allows for Standard Definition content to be played over DisplayPort to non-HDCP compliant displays.
Still no way to play legitimately purchased High Definition content from the iTunes store on a display which doesn’t support HDCP.
DRM once again exasperating legitimate, paying customers. Of course you have to be pragmatic about it, but my advice continues to be to avoid DRM infested content whenever possible.
