Still can't copy Evolution x!!!

[tdg8934]

I read most of the posts on XBOX backups. I went out and bought expensive Memorex DVD-RW's and TDK CDK CD-RW's and STILL NOTHING. I can't copy any ISO's to any media and get it to play on the XBOX. I am recording at 1x speeds on many different formats DVD-R, DVD-RW, CD-R and CD-RW and media types Samsung, Memorex, CompUSA, TDK, Aterra, generic brands too on both my Pioneer A04 DVD burner and Plextor 40/12/40A CD burner.

The XBOX says it can not recognize the media. I have an Enigma X modchip. Is there anyway to verify that it even works??

Please help!!!!!!!!!!
