I am new to all of this. So my LG 42PC3DV is a EDTV, Correct? It has HDMI input. I currently have standard dtv box R15. The dtv tech rep was right when he said i needed to upgrade to the HD DUAL TUNER DVR to get the best pic quality. Like i said im new to all this hdtv stuff. right now im hooked through svideo and the pic is very pixilated, almost like a 100kbps video stream. By getting this hd equipment i will notice a night and day difference? I HOPE SO!!!
