As always whenever I plan on buying something I always check here first I'm planning on buying a home theater system because my old 5.1's broke. (Damn hizzing and buzzing). However, during my shopping I've come across receivers that say they have Video upconversion. What does that mean really? From what I can gather, it works like an upconverting DVD Player? Makes regular DVD's look better aka similar to High Def? I have an OPPO Upconverting DIVX player and it works wonderfully. But my question is this. If this is Upconverting will it make standard def shows look better? We all know Standard Def shows look like crap blurry on an HDTV but will a receiver with Video upconversion make it look better? Or am I way off. I have HD access DirectTV HD-DVR. Which means I have like 10 HD channels and 200 standard def channels. Heres such a receiver that I'm looking at if it does: Onkyo TX-SR605 However, if that's not the case I'm probably just going to get a HTiB: Onkyo HT-SR800 7.1 Channel Home Theater System all inclusive Any help would be appreciated.
