Query: HDMI not working

I brought this camera in mid July. The pictures are great compare to other HD camera. Component connections, AV connections are workingbut when I tried to hook up with my DVI it's not work!This DVI in my HDTV is currently using with my DVD player and has no problem. I called Panasonic and after about an hour of diagnostic, theyasked me to send back in. When I asked if they have a tracing number,they said no (which meant that after I sent it to them, I may never see it again).I returned it to Amazon with $20.00 insured postage (ouch!). Amazon saidthey would refund this postage, but never did.
