HDCP problems - Bang & Ofufsen TV

Hi:-)

My Apple TV 3 want show any kind og streams or rented movies - then I get the error with the HDCP problem. A technician hooked my Aaple tv 3 up with my Beovision 7. The problem is that my Beovision have a DVI-output that can´t show HDCP even though I have a converter from DVI to HDMI. That means that I can only wathc the downloaded movies on my Macbook, listen to music and see puctures. I would really like to stream movies and rent movies fra iTunes. Is there any way that can be done?
