I am still undecided on whether to get the new Sony Grand Wega , or really go for it and get the Pioneer 502 Plasma Screen. My question is this.The Sony has DRC which improves the resolution by 4 times( but from previous enquiries cannot benefit from Progressive scan as well) - but the Pioneer has "digital high density image scaling" which apparently gives an 8 fold increase in signal density, and can accept progressive scan pictures - but do they work together? (will it effectively result in a 16 fold increase ?). Sods law it won`t, but.... Also, Hitachi Progressive scan sets - is this an entirely different technology to progressive scan , or are they really Prog scan (giving pal and NTSC benefits) God bless all who answer !!
