When you turn the camera the motion isn't smooth and my eyes start hurting because they try to focus on the screen but it's impossible due to the jitteryness (is that a word?).

EDIT: It took about 20mins to happen, but my eyes felt like they were bleeding after that...

Ever look at a DIVX film? Whenever the camera moves horizontally it jutters. Its the exact same effect, right Grass?

swiching from a 50 Hz to a 100 Hz does not improve the input signal (duh) but it does improve the output render by adding an extra frame inbetween each two "input" frames by "melting" the horizontals of the precedent and that of the following.

"Melting" is not the right word though. the added frame's horizontals are divided by two, pairs consists of the precedent frame while impairs of the following.

Yeah!

But I don't think many would think it's a big deal when watching a DIVX because:

1) They usually watch on a small screen while I'm playing on a 40" so the jutters are bigger.

2) You don't try and focus as much when watching a movie. When I played MGS4 I was watching the screen like a hawk

I did notice the jutters when watching a Blu-Ray, but it didn't bother me nearly as much as during a heavy gaming session.

Strange, because when I looked at 50Hz and 100Hz standing next to each other it was VERY obvious that one was much smoother. They were playing some animation about bees on Bluray and even my girlfriend said the difference is obvious. She doesn't know anything about anything techno related btw.

This is exactly why they tell you its 200htz preferable for watching sport on lcds and plasmas. Split second timing required.

looks like your eyes have the same sensitivity as mine, you should of gone for a Plasma TV like I have.

The 100Hz and all that crap is bullshit, it's simply a work around for the limitations of LCD technology, but it makes things move and feel fake, and in some cases causes artifacting on the image, however, it's suitable for the majority of the market which is why it's standard on LCD now days.
The other work around is to simply buy a panel with a refresh rate of 2ms, but their hard to find and usually more expensive, the most common panels are 8ms, which is why it affects sensitive eyes.

I my self went with a Plasma because when I was tv shopping I always noticed 2 things, 1) LCD colours and blacks were crap incomparison to plasma, and 2) I always saw the image stutter on LCD which no one could see except me, the Plasma sets I saw never had this issue with my eyes, and at the end of the day I went for my Panasonic plasma.

I know people will say plasma burns in, but these days it's no longer an issue as it was once, the thing is no technology is perfect. Plasma does have it's own problem, it's phosphor decay lag is one of them, in other words when an image say is panning really fast from black to white then in between where the 2 colours meet their is this green tinge, but only when the image is paning fast and only when the image has an excessive amount of black and white images, but even under these conditions it's not that noticeable....

to be honest I'd rather the flaws that plasma have than the stutter my eyes see with LCDS and no the 100hz as In said makes things smooth what it feels like the image has been speed up something like .5 and just looks unrealistic and fake, well to my eyes.... for the reason mentioned above I hold plasma technology as the pinnacle of TV tech currently around when it comes to price, size, picture quality, and inherent tech flaws...but this is just my opinion.

CRT is perfect. I still got mine, Sony Bravia Super Fine Pitch 78cm, and im keeping it because NOTHING gives the level of contrast and blacks like a crt.

Why I didn't go for Plasma:

1) We have the most expensive electrcity in the world here in South Africa and due to another government F*CK up it could increase by 400% over the next 2 years. Plasmas suck a lot more power.

2) I have a SERIOUS problem with buying anything that has a half life. My parents still use their 10y/o Sony Trinitron flatscreen and it's still great. You're plasma will be finished one day...

I know Plasma holds some very good advantages, but the above two points are just too much for me.

BTW, my LCD has 2ms response time and 200Hz, so it's really smoooth. The difference between mine and anything cheaper is obvious to me now.

But I have to agree with you, Plasmas are better for most people who game or watch sports...

EDIT: I would say LED's are the pinnacle. Wouldn't you agree?

I'm the same way except in the US it would be a 60hz and a 120hz set.  I probably would notice a slight difference if I had 20/20 vision.
