I have a 42pfl6007H/12. I plugged a 250GB Toshiba HDD. The TV recognized it and formatted it. I see it when I go to 'recording' and it says 100% free.

My TV is connected with a HDMI cable to the digital decoder box on HDMI 1. I selected the HDMI 1 source and pushed the record button on the remote but nothing happens.

Any idea why?

Thanks in advance for your help.
