Emulators on Xbox?!?!? HELP!!!!

[infidelity]

My xbox doesn't recognizes the xiso file. I used xiso, to make my nes folder contents into an xiso file. I downloaded Record Now Max, and burned the xiso image onto a DVD+RW and a CD-RW. I turned on the XBOX with thediscs inside, and I get nothing. Iturn the machine on with no disks inside, pop thetray, put the discs in, nothing. I'm starting to feel this is a joke. Could my chip be defective? I know how toput modchips in,asyou can tell at the bottom ofmy profile. Is there a boot method?? Also, this is pushing it, is there anyway I could g et a copy of your disc,or someones working emulator xbox disc?? Your help is appreciated. Thank You.
