Fiber optic DVI cable

I got a replacement HR 10-250 DirecTV HD DVR in August. Now when I hook up the DVR to my High Def TV with a hybrid Fiber-Optic DVI cable (I need an HDMI-to-DVI adapter) after 1 minute the screen goes blue and I get a message stating that the DVR has shut down due to overheating. Previously this setup had worked just fine. Did they change the circuitry in the HR 10-250? I'm wondering if the HDMI output jack can't supply the necessary 500 milliamps to the trasmitter side of the DVI cable.
