I am thinking about getting a new dvd player and was looking at progressive scan, but then started to think about other things. I have a Panasonic Viera 37pe30, so I assume on terrestrial and sky it converts the 576 signal into the 480 native screen resolution? Firstly, does anyone know what de-interlacer the pe30 has. I have emailed Panasonic but haven't got a reply yet. The Iscan Ultra seems to output 480 lines for NTSC inputs and 576 lines for PAL inputs. Is it possible to choose the lines output from either input (ie. 480 out from any input), or is this effectively what a scaler (or descaler?!) does? I suppose in a roundabout way i'm asking if the deinterlacer of the Ultra will be better than the pe30?! I've found out the Ultra uses the Silicon 504 and this is found in some of the good Denon DVDs, so I assume the answer will be yes. thanks, Owen.
