thanks for looking. just been looking at a company that can fit a SDI output to my pioneer 747 and then looked at the DVDO-ISCANplus which also has a SDI input upgrade. my questions are these.. 1. if the digital signal from a sdi output of a dvd player can go to the iscan,dose the iscan internally convert it to analog and out to the plasma?(going on the bassis the iscan will do a better job than the dvd player in converting the signal). 2. to keep the signal digital from the dvd player through the iscan and on to the plasma,can i get a sdi input fitted to my old plasma(pioneer pdp-502mxe)? any help would be great.
