Here I will try and document the various releases of the Xbox 360 HD DVD player, in reverse chronological order. Major releases are in bold (a major release either has new features or has a boat-load of changes, minor releases are pure bug fixes). To see which version you have, while playing a disc press Display then select the ? icon. Note that Dashboard releases are separate from the HD DVD player, and done by the Xbox team not the HD DVD team.
