Dave,
I had calibrated the set with VE before I upgraded the cables. Funny thing was that the colors seemed a bit off after upgrading. Also, calibrating seemed to be easier after the upgrade - I was able to get better matches on the color and hue controls and the sharpness was easier to get a good level.
Maybe it is the TV - time to upgrade!!
Isn't that always the way: The DVD player makes you _need_ a new DolbyDigital or DTS receiver, then you _need_ the powered subwoofer to get the LFE, then you _must_ get new cables to optimize the signal, which shows you how bad your TV really is, and soon new speakers can't be too far behind...
...and of course you have to have the perfect remote to control it all - which leads you to --
