Bob, let me ask you this.
Do you have to disable 480p, 720p, as well as 1080i in XBOX dash-board to play DOA3 in 480i ??
I ask because unlike rest of my titles, to play DOA3 in 480i, I have to set 480p, 720p, as well as 1080i to "NO" in the dash-board.
If I set 480p to "NO", and leave 720p, and 1080i to "YES", DOA3 doesn't show any images. Only sound comes out of speakers.
But other games like Panzer, DOAX..etc I only have to disable 480p, to play in 480i.
Kinda strange.. wondering if your XBOX behaves like this only with DOA3.
Many thanks.
