Anyone here play DDR games on XBOX with HDTV? Need help with syncing.

I just need to know, basically, how many milliseconds I should adjust the games so that they work with an HDTV of 1080p calibur. I can't imagine it would matter what brand the TV is. However, even if it does, if someone has their settings already set, just tell me what you have them set to and I'll give it a go on my XBOX. Because I can't seem to figure out if I need to add seconds or subtract seconds. Any help would be fantastic.

 

1080i is laggy on the XBOX, DDR is fast paced wouldn't be very good.

 

Sorry, it isn't full 1080i. It's the one just below that.

 

720p is the next resolution the XBOX has.
