Personally, I don't think an aftermarket chord will do much. The limiting factor will be your signal. Cable/Sat can be a bit funny.
I also have an EDTV (2-1/2 years old) Panasonic, and I love it. Nobody can tell the difference between the EDTV and true HDTV from the couch. Besides with the dearth of programming, you've saved a few thousand dollars.
