Hi I have a Sanyo PLV-Z1 with a Panasonic DVD-RV80.This DVD player have Interlace component output. Somebody told me that the Z1 have a built in processor that transform the interlace signal to a progressif one. My question is: Will I get better picture with a progressive DVD player? Happy Holidays, Huot PS is it true that the Z1 have a built in line doubler?????
