I'm sometimes forced to burn cd's for friends when connecting their xbox to my PC or xbox is not an option. If you want to burn the files with Nero or whatever as a 'Data Disc', you will need certain apps on ya xbox to read it (like media centre). However there is a good chance not all the files will copy over, say you have 30 main folders on the disc and u copy, then near the end it screws up, then its prolly cause of 1 file that the xbox dosnt want for whatever reason. In that case, I'd copy those folders one at a time, and if 1 stuffs up just skip it.
Also u need to pay attention to what cd media u use, some xbox's can read cd-r's, others only cd-rw's. Safest way is try playing a burnt music cd,if it works then your xbox will most likely read that media type.
you need a Crossover Cable to ftp to ya xbox.
