Help pls with Halo

[flynny]

Hi is anyone experiencing problems with the screen getting all jumpy and jittery when playsing Halo 3. Esp when vehicles are on the screen, they seem to jump about randomly. I have high speed bt broadband connection and have exchanged the game for new disk. Could it be problem with the x box. Other games are fine except for Fable 2 which keeps freezing. Have googled problem as much as I can but haven't found an answer...pls help
