Page 1 of THX Optimizer and DVD screen position

Yes, well I have had two 32in w/screens-a goodmans which was returned and the Panny 32DK1 which i got yesterday. The probs are that the THX optimizer on the S/W EP1 and T2 disks display the outer box on the w/screen viewer test off the left hand side of the screen. It is about an index finger width but occurs on Composite, S-vid to S-vid and S-vid to scart leads on two seperate tvs aswell as mine. Is this to be expected or a problem with the player, I have a Sony DAVS300, chipped and all that. I have carried out all tests required by the supplier and all fail. What next? Sit there and accept or push for a repair/exchange.
Any Help Gratefully accepted.
