Help, before I kill my XBOX!

[Compuhacker]

Ok, I need some help here. I installed a Matrix in my ver1 XBOX. Flashed it with evo25.bin, stuck it in, got a green flashing light, rebooted and got the blue XBOX logo. So with that blue logo Im thinking the chip is doing its job. Now heres my prob. I downloaded EvolutionX_beta_V1.8.3285, unzip all the files into a folder and made an ISO of them. Burned them to a CD-RW at 1x, stuck it in my XBOX and got the durty disk error. Went back, and reburned the files at 2x, same thing. Found another file called EvoX Install All and burned that to the CD-RW, and same error. Went and bought a new CD-RW and same damn thing. Now one thing is EvoX Install All is 74mg and my ISO is 3.7mg. Some thing I forgot to add?

This is what I put in my ISO:

bios
Skin
default.xbe
EvolutionX beta V1.8.3285.nfo
evox.ini

Is this a screw up with my ISOs? Or is it my CD-RWs? Or maybe a prob with my chip? Or is there a way I have to burn the ISOs? Using Prassi PrimoDVD 2.0 b/c the ver is Nero I have wont work with my DVD burner. The only thing I have not tried is burning the ISOs to a DVD, but in this little hick town I cant buy blank DVDs any way. Dont want to order any until I know I have this thing tweaked and working.
I'm about to take this thing out back and put about 30rounds of 7.62x39 in it. So before I do, please help.
