A friend brought over his Xbox 360 and we were surprised by the amount of aliasing seen on my TV. I have a Toshiba 46HX83. We confirmed the system was running at 1080i. We tried other resolutions as well, but the aliasing just got worse. Any ideas? We've both seen PGR3 on other TVs (including his 51" Hitachi) and there was no aliasing to be seen.
