XBMC Live
XBMC Live includes all the features of the XBMC standard edition, but comes with an embedded operating system to facilitate product demos and portable use. A system can boot from a disk with XBMC Live and run the program without writing any information to the system's hard drive. It also lets users install a bootable copy of XBMC directly onto the hardware so a computer system boots directly into the media player without any external media or configuration required.
Requirements
XBMC Live runs on Intel/AMD processors that support CD-ROM booting and Streaming SIMD Extensions. For HD playback, XMBC recommends a dual-core processor. The software also requires a graphics processor compatible with OpenGL 1.4 or newer, though OpenGL 2.0 or newer is recommended. This includes ATI, NVIDIA and Intel graphics units. XBMC Live boots with an embedded operating system and it has no specific operating system requirements.
Options
Even though Xbox users cannot use XBMC Live, advanced users can access all of XBMC's features using the standard version on an Xbox console. The recommended method of installation makes XBMC the default dashboard when powering up the system, making the program functionally identical to XBMC Live. Installing XBMC on the console requires a modded Xbox using either a softmod or a modchip, compiling the XBMC source code and transferring the files from a computer using an Ethernet connection. XBMC's website keeps specific instructions on the various methods of installation. Note that an Xbox console using XBMC cannot connect to Xbox Live because Microsoft does not allow modified consoles to connect to the service.
Use
Using XBMC on Xbox or XBMC Live on computer hardware gives users instant access to the media player, much as a home DVD player or cable television connection. In addition to playing audio and video stored on the hard drive, XBMC can play media from the Internet or stream media from another networked device. Custom skins add a user-defined look to the software and are available for download from the XBMC website.
