1)   I created the disk originally with Roxio Easy CD Creator 6.0 .    
CD Creator's default behavior for a "Mixed Mode Disk Project" is to 
place the data track first, and then the audio track(s).  

2)   Using Easy CD Creator, I then made an image file in Roxio .CIF 
format because the widely used and nearly universal.ISO format only 
supports data-onlyCDs; not audio or mixed-mode disks.

3)   I initially only posted the disk image in the Adaptec/Roxio .CIF 

4)   Someone else then converted the .CIF image to Nero .NRG format 
using a third-party format-conversion utility. Given that all the 
complaints so far on various lists has involved disks made from the Nero 
version, I am wondering if the CIF->NRG conversion was less than 
perfect.  I simply have no way of knowing if the conversion was 
perfectly accurate.  Since I don't have or use Nero Burning ROM, I can't 
test or vouch for the .NRG version of the file.


5)   Win 2000's "CD Player" applet (not Media Player) plays the disk 
just fine, allowing you to easily skip over the first (data) track that 
some CD drives mistakenly think is an unplayable audio track.    The 
applet "CDplayer.exe" produces a user interface that looks like a 
typical car stereo CD player.  It is a single 330K exe file located in 
the /SYSTEM32 subdirectory underneath the main Windows directory.    
This file requires no installation or hooks to the Windows registry.  It 
can be copied from a Win 2K system and easily used with Windows XP.
