CDI2Nero and Single Session CDI's ?

[Pow]

I seem to have problems with games which only have 1 session (or at least that's what it says in CDI2Nero). After I burn them the DC doesn't recognise them as games, and tries to play them as Audio CD's. An example of this is Sonic Adventure 1.

Is there a tool that would let me change this (ie add andother 'dummy' type session), or do these simply not work with CDi2Nero.

I can't use discjuggler, it straight up refuses to work with my kit.

Any suggestions?
