Solution for the jitters...

In a previous reply ( 2 days ago ) I mentioned that I didn't have any jittering problem using my TV capture card. But it was just after a quick test in time trial mode ( I came back home with my brand new copy of the game at 23:00h ). Yesterday I tried a few races in beginners mode, but before racing I increased the brightness by 2 notches:
Autumn ring mini II: no jittering
high speed ring: no jittering
SS5 II: jittering .
So, it seems that the BUG is TV independent because it even happens with a TV capture card.
But what really puzzled me is that some people could get rid of the problem by decreasing the brightness because jittering is caused by some wrong timing and or synchronization ,and the brightness of each pixel has nothing to do with that.
I know a little about 3D graphics programming ( At least I can program a textured rotating cube using OpenGL )
But hey, if it solves the problem , I have nothing to loose by trying that solution.
Thanks for the tip

Didn't work for me. Adjusting the brightness did nothing. Thankfully, I've only had jittering during gameplay only once on SSR5.
One other comment, when completing a race and the grid comes onto the screen showing where each car places, I usually like to change the car view to 3rd person and hit the button to watch my car cruise around the track. By hitting the back view button while that grid is on the screen, it would immediately start jittering. If I let go of the button, no more jittering.
Could it be the resources of the PS2 is stretched so far that when all the cars are on the screen, with all those reflections, and any input from the DS2 with cause this issue?

I think its an issue with the television sets. I have no jittering issues, but at SS5, it does seem to bog down for a split second, no jitters tho.
And yes, I am watching it in 1080i HD for those that said if I can select between interlaced, progressive, cinemotion. I hate the way it switches got 480 when going back to the menus tho.

turning the brightness from 3 to 0 helped me greatly. I was getting jitters a lot during the start of races, some replays, and a LOT in 2p battle. turning me brightness down has made the problem almost nonexistent. happens once in a while, but not like it was.
Turning the brightness down to 0 did nothing for me... I think we will just have to live with the Jitters...
EDIT: This is my second copy too... First copy did the Jitters as well. Second copy is jittering too. (I got a new copy due to the Intro being an absolute nightmare. Totally skipping like crazy! New one seems to be ok... HOPEFULLY!)

If you look back or to the side (using the D-pad on the DFP, I don't know what the default button is for it on the DS2) the jittering will stop immediately.
Another thing to try:
I tried turning the brightness down also, but was still getting jitters, may have helped a little, but not much.
I noticed that the jitters happen at the start of the race, what else is happening then? The music track is being selected. I have all BG music set at 0, but it still tells me what track is playing in the corner at the start of the race, so it's still playing the song, just with a volume of 0.
What I did to stop this:
Go into the jukebox section in GT mode and delete all songs from the race playlist. I have been 100% jitter free since I did this (although I haven't raced SSR5 since, and that seemed to be the worst offender). Hope that helps some.

I have the music turned off at the jukebox, and still get jitters. It has nothing to do with music tracks. My worst jitters offender is the Opera track. In the beginning of a race, I actually had to stop and pause the game one time, because my eyes went bananas, trying to adjust to the crazy jitter crap.
Biased turkey
Of course it is TV independant (although, it may not be video standards independant, since 480p shouldnt have interlacing obviously).
The way the PS2 is setup is that developers render to half height framebuffers, in order to save on fill rate costs. Whereas say, an Xbox or other consoles will render the full 640x448 framebuffer each frame, the PS2 (in GT4/480i) is setup to render 640x224 each frame (or some other width by 224). What that means is as long as the game is running 60fps, the end user will never know the difference since the odd/even fields are always showing the most up to date image.
However, the issue is when the game drops below 60fps...at that point, some fields are going to be old...the video hardware will be showing a old frame buffer and things get out of synch, thus the pronounced interlacing.
I like the theory about the brightness, I'll give that a try tonight. It may very well be that they are doing the brightness controls by doing a postprocess on the framebuffer (ie, use the frame as a texture, and then render a full screen textured polygon with over-bright vertex colors to increase brightness). If you set that to zero, I bet they've got it setup so that post-process doesnt happen. While that probably only takes 0.1-0.2 miliseconds, you only have 16.7 (1000ms / 60 frames, for 60fps) to work with each frame so in many cases that extra hair of time may be just enough to keep the game running 60fps. I dunno anything about the PAL version, but this may very well mean the PAL versions will have no such issues since they run at 50fps, and therefore have 20ms each frame for calculation.
Anyway, thats the laymans guide to how it all works. 480p guys should be fine either way.
I tried the brightness thing. Still no difference. The game still jitters with me.

I tried the brightness thing at Vegas where I know the jitters happen. When i turn the brightness to +1 i get jitters, 0 no jitters, -1 jitters. Same thing happens with contrast. I still get jitters sometimes wiith brightness and contrast set to 0 but they disappear after I do a full lap.

Pissed about what dude? The fact that you spend $2000 on an HDTV just so you could play a game on it? Yeah, that would make me upset too I guess, but mostly because I'd have no other use for the TV other than the game and I'd have trouble justifying that cost.
I use my HDTV for a LOT of other things. Movies through an up-converting DVD player in 1080i (or any other resolution I choose), HDTV through an over-the-air tuner, and HDTV through my cable service. I use it most for what HDTV was intended for: SPORTS.
I didn't buy the TV specifically for GT4, but being able to use the HDTV option is just a nice added bonus. Believe me, if you watch a football game, baseball game, NASCAR, or even Law & Order in HDTV you'll be glad you spent the money.
And GT4 is the only thing I've ever seen cause this type of a problem. It is in the game's coding, and if it doesn't do it while you're actually racing, then what's the big deal? A little bit of fouled-up interlacing isn't going to make the game disc, your PS2 or your TV self-destruct.
But then there are lots of people out there who have to complain about SOMETHING. I guess that's what this thread is for. I'm spent.
I have a 20inches Toshiba 2 years old and have the Jitters with the gae on some places. At SSR5 like most of you but on Laguna Seca also and at some rolling starts on some of the japanese speedway ( Fuji, Tsukuba... don't remember which one...) I tried to turn down the brightness but it didn't help.
Damn it I don't want to play the game in this state... I mean I feel like PD just did quite a lame job these past months. I can't imagine playing the game this way for years to come as I did with GT3...
