All right thanks a lot for the info. Now coming back to the format issue, if I use a 10bit uncompressed setting, then my image size goes to 720×576 (I am in Switzerland and the format is PAL). My actual Hi Rez picture is at only approx 30 percent of its original size in order to fill the screen, that I understand. However if I choose a HD setting the image is at a higher percentage as far as size and also a much better quality, it is quite a lot crispier. What is this due to? My main concern is to make sure that when this will be projected onto a large screen approx 30 x 20 feet I will not have jagged edges everywhere, specially knowing that I started from hi rez images. Thank you.
