I use my older P4 pc as a torrent box/internet only, with MSE and deepfreeze installed to check them for viruses. it has become my main download PC/gateway for downloaded content.
I too, have an old XBOX with XBMC on it, and have it networked to my main PC. XBMC is great software, and bring s life into an old console! and it still plays games! i found the networking of the XBMC very easy, even with a lacking experience in that area.
How does one go about setting up XBMC on an XBOX? I have an old XBOX as well and since I play about as much on it as I do on my gaming rig, I figure that both should have it and only my gaming rig has it currently. I am relatively sure that the LiveCD version of XBMC will boot on it, but I doubt that it would perform as well as an installed version on the XBOX's hard disk.
i followed these specific instructions, found here:http://www.productwiki.com/microsoft-xb ... nutes.html
Very good, and only costs the cheapie game and xbox gamesharky thing. basically, you will load a saved game thru a listed, compatible game, and in loading the save, it actually runs an installer, allowing you to "soft-mod" your xbox. it creates different partitions, and is relatively easy the 2nd or third time. the same software save can be used to revert your software back to original workings, if you ever needed to. Thankfully, i never sold my older games back, cause i had a copy of MechAssault that worked with the modding process.
i also use the controller, as well as the DVD playback kit (remote and IR receiver)
NOTE: as I have followed the previous instructions, i visited the website of XBMC, and found some cool skins. will those newer skins work on the XBOX if i FTP it over?
