Hello. Perhaps Gordon or Joe can help me with this. I have a Panny PWD5 42" Plasma but am considering upgrading it to a High Definition model. If I were to couple this with a scaler, would I benefit from a better picture? I am also considering moving up to a 50" model. Does this make the earlier question redundant? Are all the 50" plasmas High Def anyway. Finally, does the Pioneer 50" offer anything remarkable that the panny does not (a working DVI connection for a start). Many thanks, Gerald.
