I've just ordered a 27" RCA LCD TV, model LCDX2722W, which has a 1280 x 720 resolution panel . When reviewing the features it says: "The advanced de-interlacer progressively converts incoming signals and up converts to 720 progressive line panel with 25ms response time." Is this a good thing? Will it potentially improve on digital cable TV signals? How about old VCR tapes? Thanks.
