/**
|
||
|
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,
