Ooops, let me clarify my question.
What version of WMP should I be running in Win 98 and in Win 2000 to avoid conflict with Nero/InCD or DirectCD/EasyCD, only one pair of which would be on the system?
I asked because I found the following in the InCD files:
"InCD is not compatible with the 'Adaptec CD-Burning Plug-in' which is installed as part of Windows Media Player 7.x. Please uninstall the plug-in using 'Add/Remove Programs' from the Control Panel."
