Upscale and upsonvert can be confusing especially in the context of receivers. I think upconverting on the Pioneer refers to taking a component, svideo, or composite input and upconverting it to hdmi. Scaling most often we are talking about upscaling here will involve changing the resolution and or interlacing/deinterlacing settings.
As mentioned in several posts this is a global setting and it messes with things it shouldn't even touch. I have seen a straight digital signal at 1080i on hdmi suffer as a result of Video Conversion.
My A1 HD and SD video gets degraded just because Video Conversion is on evem if it is set to 1080i. Now if the signal is already HDMI and already 1080i at the source why should Video Converison matter or why should it even do anthing but pass it through unmolested... but it does not pass it through unmolested. It just totally crushes the blacks on my Tosh. I leave Video Conversion off 100% of the time now.
Pioneer ought to be embarrassed by the video section on these recievers. That capability is hardly worth of the label Elite. If I had figured it out within my return period this reciever would have went back.. just terrible.....
