[WinMac] More on cross platform CDs

I've been following the thread about cross platform CDs and just
yesterday tried to create one and was not entirely successful. I've
made cross platform CDs before but not with long Win95 & NT filenames.

Here's what I've did...

First attempt: using Toast version 3.0.5 on the Mac I made a hybrid CD,
HFS and ISO. The ISO side truncated the longer filenames but the Mac
side was fine.

Second attempt: I burned just the Mac HFS partition on Toast not closing
the disc and then took the CD to my WinNT machine that has a writable CD
and wrote the ISO partition there using Easy CD Pro 2.11. I did NOT
close the disc then either. This time I was able to get the long
filenames as that's one of the options when you write the CD in Easy CD
Pro, an option I did not see in Toast 3.0.5. The CD works fine on both
platforms except the Mac sees both partitions. That's what I mean by
not entirely successful. Before when I've made dual platform CDs in
Toast the Mac would only see the Mac partition. Is this because Toast
didn't write the whole thing or because I didn't close the CD on the
Windows side? Or should I have written the Windows partition first and
then finished by writing and closing the disc in Toast?

Another problem with this second attempt CD was when I tried to
duplicate it in a CD duplicator it only duped the Mac partition and not
the Windows partition. This is the first time I had tried to dupe a
dual partition CD that I had made in that duplicator though I don't
think it's any fault of the duplicator. Could it have been because I
never closed the CD when writing the last partition to it? I'm guessing
that the duplicator works by copying an image of the CD and not byte for byte.

Third attempt: I took the ISO file created by Easy CD Pro and copied it
to the Mac that has Toast. Using Creator Changer I made the file have
the same Type & Creator code as an ISO file made by Toast. I then made
another dual CD with Toast, HFS & ISO and it seemed to work fine but
when I put the CD into my Windows computer it could not read the disc at
all. The Mac partition worked fine.

Any suggestions would be greatly appreciated.
