Ultrastudio mini recorder doesn't work

I have a mac mini i7 ivybridge quad core 16 gb ram.
I connected a BlackMagic ultrastudio mini recorder (HDMI input to thunderbolt output) to capture panasonic HDC SD700. BoinxTv recognize the BlackMagic trough mac mini thunderbolt input but the camera screen on BoinxTv is black.
I set up the camera HDMI output to 1080i. Into BoinxTv “source setup” the input is recognized as: component yCbCr 8 bit 422 size 720x486.
Can you help me?
Thanks in advance
