Took delivery last week and either the sets faulty or I am

and was hoping you could tell me which (this is on top of the probs in another post).
I cannot save any settings at all. TV always comes on in pal mode and then have to manually change it, even if I save the setiings, next time I change to analogue or turn the tv off, it still comes back on in pan.
Very very blocky picture, and DNM etc do not seem to make any difference, again, try and save picture settings and they sometimes seem to save, but turn tv off then back on and settings have reverted to factory set ones.
Watching Emmerdale last night, (sorry, wife watching Emmerdale last night

)and when the actors moved there hands, there was a definate smearing behind them, like you can select trails on your mouse and no amount of changing picture options cured it.
Can someone let me have there preferred settings for watching tv and for watching footy.
The tv is being exchanged next week anyway due to a 'cracking' that occasionally happens so not too bothered about these other 'features' (Ha, used to own an FQ75, can you tell) but I would like to know if next tv will have them as well.
