xbox iso's and burning

[Jenn]

sorry guys for being such a newbie, lol but here is the problem now, i wanted to create a multi game disc, i used craxtion , selected the multi game disc option, added the files from both games and when complete i ended up with two seperate iso's game 1 and game 2 iso's is this correct? When i used the data burn method, with record now max i just chose both iso's and added them and burned the game, and didn't work, I am not sure what i am doing which i assume is quite obvious to you guys, lol
what do i do with craxtion, the proper settings?
what do i use to burn the iso's?
and shoudl i have gotten seperate iso's for a multi game cd?
What program do i use to make the PNG files? or images
Thanks again guys your all great for helping
