/**
This is necessary because CD-I or VCD disks are not correctly
mounted by the linux kernel.
Windows seems to do it correct (sometimes, the other time it nearly crash)
During my test I found out that CD-I and VCD seems to be different.
One works with the CD-I loader the other with the VCD loader.
This class tries to find out if its a CD-I / VCD stream.
Then you can set the interface and load from this interface.
This class depends on the reader routines from xreadcdi/ xreadvcd,

The code is used in a few other packages, in which I looked as well.
