I've also had a few guys ask for clarification on the driver, so I'll answer those here:
1) This driver works on all OS versions that support c4z drivers, so this means 2.6 and newer, including 3.0. I just timed the release of this driver with the release of OS3.0.
2) The File Name says V4, which refers to the version of Apple TV Hardware. This driver will work on V3 and older Apple TV's, but is optomized for the new Apple TV hardware, that have the thick hardware, and includes the Apple TV App Store.
3) V6 is the driver revision, which includes the latest discrete reboot / resolution commands, as well as new 3D graphics/icons. The previous version was V4, and did not include the new graphics, and discrete reboot/resolution commands. V5 was an unreleased beta version which had flat icons.
4) This driver has been tested on HC800, and all EA processors. Due to the unique and precise nature of some of the commands, using special repeat rates, performance of this driver for the specialy commands like Jump Home, Wiggle Icons, and press & holds on arrow keys for fast scrolling may not work on older processors like the HC200/300/500 and the HC250.
