I will be working with a Digital Projection Ivision HDX DLP projector and a modified Pioneer Elite 59-AVi for multi-region capability. I would basically like to know if SDI output is reccommended for better picture quality with the above hardware? The reason being, because I've come accross the following site which offers an already modified multi-region 59-AVi w/ SDI output however I'm skeptical of purchasing a moded high-end player from an online retailer: http://www.jvb.nl/jvb.asp?cur=1&level=dvdplayers&page=title&title=206 I've been told by a friend that I do NOT need to SDI mod the 59-AVi because it can pass 480i through HDMI, yielding the exact same results has an SDI mod. Is this true? Now moving onto video scalers... I've been recommended the HD Leeza but would first like to make sure that this would be the ideal choice with my DVD player. I need a scaler which is able to accept 480i over DVI/HDMI and apparently scalers such as the iScan HD are not! I'm not much of a tech head and only have a very basic understanding of all of this, so if someone could please explain in simple form and offer suggestions, it would be really appreciated. I can get a REALLY cheap HD Leeza scaler but I want to make sure this would be the choice for my Pio 59-AVi and would also like to know whether or not SDI modding the player would be a waste based on what I was told, or if it'd be of benefit in conjunction with the HD Leeza video scaler... I'd like to keep a digital signal all the way through if possible for optimal image display. Thanks in advance!!!!
