I am trying to decide whether an Iscan Pro or the Panasonic STB is the best way to improve my picture. Just bought the Mits 65809. Lousy picture with satelite channels (or OTA for that matter). Iscan only doubles to 480P whereas STBs upconvert to 720P or 1080i. Would the 480P Iscan picture be better or worse than a 720P or 1080i STP upconverted image. I realize that the STB will also decode the HDTV signal (few as they are now) and I intend to buy one in the near future anyway. the question is whether the improved picture from the Iscan is worth the money. Any suggestions appreciated.
