I believe that there must be different settings for SD, especially for poorer quality SD feeds. As we all know not all SD feeds are the same... Sometimes you'd even have a great pic from a news studio with a crap PNP with horrendous quality..
Anyway, I hope that you can help. Some of my SD feeds look like garbage.. and look much better on a normal SD CRT set. For good quality feeds the difference if minimal.
First, CRT and LCD technology is apples and oranges. SD was meant to look good on CRTs and HD to look great on HDTVs.
The quality of an SD picture will vary, as you have said, by the source feed, but also by which mechanism is being used to upconvert it. Since your xbr (and you didn't say what size you have) is a native 1080p device, conversion of the 480i signal must be performed before it hits your panel.
Either the XBR upconverts it from 480i, which it will, or another device will have to do it, such as an A/V receiver, STB, DVD player, etc. Unfortunately, the XBR does only a mediocre job of upconverting. I have my STB upconvert all SD signals to 1080i and pass it on to the TV, but even it doesn't do a great job. There are some players and receivers that use high-end video processors to upconvert such as Reon and Faroudja, but they're costly ($1000+).
So what to do?? On your xbr, there is a setting called "Noise_Reduction" (NR). I set it to LOW for SD broadcasts and it cleans it up nicely. But other than that, there's really not much more you can do. Be aware, though, that the NR setting can and often does interfere with PQ on HD material, especially blue ray, hd dvd and some video games. Turn NR to OFF for those sources.
My advice is to rid your life of SD as quickly and completely as possible. Find the right cable/satellite or OTA HD package for you and forget about SD. This past weekend for 3 staright days, I watched a lot of sports on my xbr and watched every minute of it on HD (I felt like a school girl with a cell phone). Then, on Monday, I walked in the room and my son had an SD channel on and I cried like a baby and began vomitting uncontrolablly.
I HATE SD.
Hope this helps,
