For some reason, my default Windows XP path had been erased, leaving me with paths to Ulead's MPEG and DVD directories. To make matters worse, I couldn't find any site among the first three pages turned out by a Google search.
Anyway, if something like this happens to you, here's the default Windows XP path:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem
You'll find the default system variables here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
