That's the theory but as Nismo says, there have been reports that some games run smoother at 480i/p.Kronologic said:I cant see there being a problem at 720p (Im on a 480p TV atm) as all games (except PGR3 for some reason) are rendered at 720p. The 360 then upconverts/downconverts the output as nessisary.
I have had no issues at 480i/p
