After enquiring about the purchase of a Toshiba TDP-42WP16 I was told that this particular model has been updated to a TDP-42WP7B. After asking the differences it became apparent that Its exactely the same but this particular plasma adjusts automatically to the brightness of the room, and you're only able to use a series 5 tuner with it!!! This seems to be a bit of a cheeky thing to do, obviously panasonic are trying to effectively corner the market or for some reason they think that there grasp on the plama market means that they can do something like this. However this brings me to the question the plasmas must have S-Video inputs and the other relevent inputs, so can i use a conventional tuner on it, with out having to buy the over priced series 5. Any feed back on this subject would be gratefully recieved.
