You got it Goldflow. Its not the 955. Its HDTV sets in general. HDTV sets is meant for HDTV programming. HDTV sets picks up the SD signal and clearly displays it. What you see is all the problems with sd material. Analog sets cannot see these problems because it does not have the capabitlities to do so (not digital).
Here is the rub. Some tv sets displays BETTER sd then others. Why you ask? Simple. Its the hardware the manufactorers use in their sets. Supposedly Sony uses the best (Digital Reality Circuitry as well as a few other devices) followed by panasonic. The 910/960/955 all use this tech (the 960 is adjustable).
In the next few years will they make new tv's with better abilities to view sd programming? Maybe next years models, but i dont see them investing alot of money in research because HDTV will be here soon (5 years maybe?)
OK I have been scrolling through these pages reading info and I have to start responding. There is some great info here but no offense there is some incorrect info too. If this has already been addressed in the pages following, I apologize in advance for the redundancy.
Lets start with the above statement.
Some background, NTSC and SD programming carry the same inherent resolution - 480i. In theory and generally in practice, the digital transmission of the image allows for a better product on the receiving end. The resolution is still essentially the same tho.
All of the sets discussed in this thread 34-910 & 960 and both the XS models are ANALOG display devices. Most CRT displays are pure analog devices while some could be termed as quasi-digital. Because of the way a CRT produces its image IMO no CRT could every be described as a fully digital device.
On a side note, the defined HD signal itself does not require that the signal be applied digitally(although any other known way is so bandwidth inefficient that they are borderline impossible) merely that the signal itself contains much more information and therefore creates a more defined(high def) image. There are currently still some very expensive analog CRT projectors that can still trounce the performance of even the most expensive digital display devices. Digital devices generally have a defined reolution, analog devices can have widely varied resolution potential. A hi-def signal can be displayed on either an analog or digital device if its resolution is high enough.
That aside I believe what you were trying to say is that the 960 and both XS models have such high resolution that they tend to more easily expose weaknesses in the relatively low res input signal.
The most logical place to look for the source of problems in displaying SD images on these sets is the interface between the QAM signal and the display output on the set.

Depends on the material. With high-def programming, I don't see any sort of grid-like structure, and the image doesn't become blocky as I approach, just soft and a little noisy. .........
For cable, I'm going to get a set-top box tomorrow afternoon, but in the meantime, I have coax plugged directly into the set and was using the built-in QAM tuner to view high-def programming.
I also wanted to address some comments made earlier about poor(or similar performance) of some HD channels off the rf cable feed from the wall made by Adam. Now Adam you later changed your opinion of the hi-def performance. If your cable company is setup the way mine is, with your rf cable connected from the wall, you are not getting any hi-def signals through the cable. The 960 and XS series have built-in OTA hi-def tuners and QAM tuners. OTA works with antenna derived hi-def signals and QAM tuners decode either SD or HD signals transmitted via cable. If you hooked up an antenna and had a hi-def station in your area you could have viewed hi-def without assistance from the cable company. The QAM tuner however will only allow you to view hi-def signals that the cable company is allowing you to view. Having the QAM tuner built in is like having an unauthorized cable abox in your tv. You were likely recieving a SD view of a hi-def channel. You are not gonna get the full high-def signal from the cable company until they authorize it via their own STB. So after receiving the hi-def cable box those channels should have looked much better.
Hope that makes sense.
