I have a Toshiba 50X81HD TV very happy the the picture tv has a upconverter takes 480i turns it into 540p . I wonder is it better to run 540i into it or stick with 480i dvd player. I have a elcheapo sony $199 model A year old . I am thinking of up grading ......but I am very happy with the picture . What would be a good unit ??? to go too .
