The Chronicles of Riddick on the XBOX 360 HD-DVD Player is extremely GOOD in comparison to the Toshiba HD-DVD Player (either component or HDMI). I was actually very surprised at how well it holds up to the HDMI on the Toshiba. Riddick features tons of special effects such as the opening scene with the Lord Marshall launching the Necromonger weapon. The level of detail present on the armor attached to the hand is crisp and sharp. The armor comes off as being worn, dark and dingy. The first scene featuring Riddick running from Tombs on the Ice Planet is also right on the money in comparison to the Toshiba Player. If you have seen the HD version, the planet surface is actually a purple/blue tint from the ultraviolet light that reflects off the surface of the planet. The Ice looks crisp and very cold. The 360 delivers nearly the same experience as the Toshiba Player.
