Hi. My XBOX has very strange problems. And it is very difficult to judge the problem. Here are some facts I've found so far. 1. Only on DOA3, and DOAX 'white-transparent' vertial line are noticeable. This is only noticable where there're trees, grass, and walls of cliff. - Looks like some sort of noise. (very hard to describe). 2. The vertical lines are noticable only when camera pans. 3. It is noticable only in 480p mode. In 480i, it is not noticable. - Fine in 480i. 4. It is only noticable on 'Dead or alive 3', and 'Dead or Alive Extreme Beach Volleyball'. (in 480p mode) 5. Other games are fine. - World Series Baseball 2k3 in 480p mode, as wel as 720p shows no such vertical lines. Panzer Dragoon Orta's fine as well. 6. I doubted my display, so I've tried GameCube, and GameCube does not show anything like that. - Fine. 7. I've tried different component video cables, but no luck. Is my XBOX faulty ? I mean if it is, why only on DOA sereis ? By any chance, is this a known issue on DOA in 480p mode ? (Like fixed patter noise on Zelda : WW on GameCube in 480p mode ? - visible only when there're fogs. - dithering ).. Any comments, opinions, experience would be greatly appreciated.
