I purchased the PT51HX40C - 4:3 last Feb/2001. Everthing was working as per advertisements...great picture (after ISF Cal)...good 16:9 DVD picture... etc.... In Canada Rogers Cable has just introduced HD on the SA HD2000 Box, which I obtained in Dec./2001. The HD signals is connected with component cables into Component 1 and SD signals connected via an S-Video into output 1. In order to view the HD I switch between the 2 modes, which I think is just the way this particular TV is setup. I can live with this. In HD mode 1080 signals appear full screen, awesome quality, but verically compressed, and 480 signals are vertically compressed with vertical letterboxing. The ASPECT button on the Panny remote does nothing and HD2000 box does not have an aspect correction. Doe anyone have any thoughts on how to convert the picture to proper dimensions such as 1080 to 16:9 and 480 the same?. Am I missing something?
