Ahhhh!!!!! Don't follow this advice.
Currently there is no better chip for a Newbie than a SmartXX (though Xenium has closed the gap quite a bit with its new OS release). Xecuter 2.3 cannot compete. But in a matter of days or weeks Xecuter 3 will be out (the PCBs are finalized and in production) and it beats out every other chip currently out in terms of features and ease of use.
Hold off until Xecuter 3 is in stores. BUY IT FROM AN AUTHORIZED RESELLER WHICH WILL BE LISTED ON THEIR WEBSITE!!!
And still, there's no way around it. You will simply HAVE TO go to the tutorial section of
www.xbox-scene.com and read a bunch of stuff. Here are some things you will need tutorials for off the top of my head:
1- How to determine what version of Xbox you have.
2- How to install a chip (including where and how to solder to the D0 point)
3- How to prepare a new hard drive to work in the Xbox
4- How to set up network shares so you can stream videos and music from your computer to Xbox Media Center (This is an absolute must. My wife now uses my Xbox more than I do thanks to Xbox Media Center. It's that cool.)
5- Read all the stuff about networking to Xbox Media Center again because you won't get it right the first time.
Anyway, if you run into any specific questions I'd be happy to try to help. Feel free to PM me in case I'm not monitoring the forum.
