Hello - I have an hdtv that supports 480p and 1080i - I have run the xbox on this tv for quite a while on component video cables - getting hdtv out of the games that support it with no problems etc... Now that I have an xecutor 3 installed - the machine boots up - and things look ok - I'm not sure what mode the boot up screen is in but anyway - if i enable only 480p mode, then as soon as it switches to evox dash - the sync goes out of range and I get garbage on the screen - if I enable only 1080i mode - things seem to work ok for the most part - except, when I use the media center (one of my main reasons for modding....) the sync goes out of range... As far as I know - the video should work fine with 480p and 1080i enabled, but I get out of sync problems... Anything to check/setup etc. to fix this? I could run in straight composite mode, but many games do look _much_ better in the hdtv modes.... Any ideas? Thanks.
