Hi Guys, I have my TV connected to a upscaling DVD then my Dbox2, my picture when my DVD is switched off comes through AV2 however when I power up my DVD and change to AV4 to which my DVD hd input is connected the picture seems a lot more crisper and sharper. Is this just like a enhancer or is this as close to HD as I am going to get..Not really a massive issue but I thougth I would ask, thanks to all......
