Im my opinion, its better to make multidvd manually with 2 proggys, not Craxtion.
Since all I make are multidvds this is what to do. I have never had a problem yet. I assume you have your games that you would like to back up in their own folder along with a vid file named "mxm_ss" and a xml file named "mxm."
Next you would want to make an empty folder, name it what you want. In here there should also be a xml file called "mxm" and a copy of the latest "MXM.xbe", you would then rename the "mxm.xbe" to "default.xbe"
Now take the games that you have and the skins that you would like to use and drop them in the new folder. ex
mxm.xml
default.xbe
skin 1
skin 2
gamefolder 1
gamefolder 2
gamefolder 3
Now take SimpleXiso and make the Iso from the files.
Open the finished Iso up with Nero and burn.
Total time should be around 25 min. (making iso to burning)
Hope this helps.
P.S.
1 more thing the "mxm.xml" file in the root dir should contain something like this--------
<Config>
<Main>
<DiscTitle>XBOX GAME DVD DISC</DiscTitle>
<DiscSubtitle>NBA JAM 2004- SOUL CALIBUR 2-WWE RAW 2</DiscSubtitle>
</Main>
</Config>
The "mxm.xml" in the root of your games folder should look something like this-----
<Config>
<Main>
<DiscTitle>NBA Jam</DiscTitle>
<DiscSubtitle>Basketball</DiscSubtitle>
<//Main>
</Config>
