143 What's about Video-CD and CD-I? Special Considerations To Play Green Book
Green Book is not entirely supported on PCs, because Green Book format
cannot be read as a standard ISO-9660 CD (meaning no readable directory).
Therefore, some CD drive manufacturers did not build Green Book format
support into their CD drive hardware. These CD drives cannot read Green
Book format. They must be replaced to play Green Book CDs.
Panasonic and Matsushita drives typically do not support Green Book.
Unfortunately, many of these drives were distributed by Creative Labs
with their multimedia upgrade packages. When selecting a drive, make
certain that it is "CD-i compatible". Most CD drives are.
The error most attributable to the CD-ROM hardware problem is the now
infamous MMSYSTEM001: External Error. This is a general catch-all error
which means that the CD-ROM drive is not responding properly. The most
likely reason is that the drive simply can't read the disk.
That's not all!
Windows 3.1 CD drivers, using the file MSCDEX.EXE, supported Green Book
format. As long as the CD drive hardware could read Green Book, you can
playback a Green Book CD without problems. Windows 3.1 was such a nice,
friendly operating system.
Then came Windows 95, touted to us as being 100% compatible with Win 3.1.
Except for one thing! Microsoft didn't tell us that Green Book support
was removed from the Windows 95 CD drivers!
So, Green Book CDs are specifically not supported in Windows 95.
That doesn't mean you won't be able to use Windows 95 to play Green Book
in the future. But, Microsoft has to release a new driver or another fix
must be found. It is believed that you may be able to use the Windows 3.1
MSCDEX drivers, and disable the Windows 95 CD drivers. This is all being
tested now, so we will cover this point in a later revision to this FAQ.
