Got a new Tosh 51hx83 16x9 RPTV and love it. Problem is I don't know if I have the best picture yet. I have the TV and (non-progressive scan) dvd player connected with good component cables. I see he tv menu has a 1080i OR 540p selection. Is this 540p the progressive scan setting for the best DVD picture? I don't need a progressive scan player too do I? Everything was set up with a S & V calib disc and looks good but the manual is not clear on the 540p thing. I play mostly WS DVDs and want the best picture possible. Also, which of the 4 selectable picture settings is right to view WS DVDs in their correct aspect. Any Tosh techs out there? Thanks in advance.
