I have a hand-me-down LCD - sony KLV S32A10. Online info says it's HD ready. There's no HDMI input, just a few S-video, composite and the chroma inputs. So, are any of these inputs going to improve the picture quality of the PS3? Not shelling out cash for a TV with HDMI! ATM I'm just using the standard cable that comes with the unit into the AV.
