Just finished tweaking my new toy- the Iscan HD+ Finally managed to feed PAL 576p from my Denon 3910 to the dvi board of my Panny. Glad it does, because using ntsc 480p looked bad (while 540p was fine), something I fail to understand... For PAL 576p: Changed one of the many tweakings- HFRONT from 12 to 115, was all, took some time to get there with no pic... Brilliant and superclean picture now, worthwile improvement for both dvd and sat (yuv = component). Main difference vs yuv is the cleaner colors, not so much the sharpness which is also very good when analog out is selected. Again, ntsc 480p looked dreadful. Even my vcr shows a good picture now. Next I'll try to feed RGB from my SVHS recorder. What I love about this scaler is the tweakability and continuous pan & zoom buttons. Thought it should be possible to to call several user settings, like for zoom settings, anyone? What I don't like is the IR receiver which seems half blind, even standing in front I often must push several times for something to happen, even worse so with my Axim ccf based remote. My Axim works fine with all other kit, even on the difficult Panny plasma.
