Can't copy autoboot made with nero

I've got canon spike, capVSsnk, Ultimate vighting, and some others games that I can't burn with disc juggler 2.00.409. Neither nero 5.0.3.8 or cdrwin.
The guy from who I have these games made the image with disc juggler, then burned it with nero. And on my Yamaha 4416S or on my Goldstar 40X I can't find the game !! It says to me that there is only 1 session, with an audio track (2sec) and nothing else !!!
Help me to see the 2nd session on my PC, please ;o(


Bye

PS; I'm french, so excuse me for my poor english ;o)
