Not being fimular with Ieee recording I'm starting to learn a few things. The owners manual (page 82) describes a A/V Disk. I've found that to be more than just a simple Hard drive attached via the ieee port. Found some interisting links... might want to check them out...
what's the model number of the TV? Is one of these a ieee 1394 output and one a 1394 input? you would need a recorder like this... http://ultimateavmag.com/dvhsvcrs/39/
