I have the Panasonic TH37PW7 panel. Now I know this panel isn't HD ready but is it HD compatible as such? If/when HD becomes available via Sky and I buy a new HD Sky box will I still be able to view this HD content (obviously not shown as proper HD) on my panny? I would presume the panny would "scale" this down to SD? Right/wrong? If so is there any situation where this would be incompatible?
