Can't burn selfboot disc by discJuggler V2.00.430-FTU

I'm using the Mitisumi 4804 CD-writter, I use "CD player to CD recorder" to burn the SB disc. It success to burn the disc but it can't work in my Dreamcast?? Any problem on the setting? The other problem is some copied game can't read in my CD-Rom "Creative 36X". Those games can read in my friend's CD-Rom "Creative 52X". Any one tell me why??

use "cd from same recorder", it is the safest way i have found.
and some slower readers wont read some games for some reason..i have the same prob over here, but i have 3 systems burning and only one has a 32x reader the others have 48x
