Well, X, I've been using version 5 on XP Pro for about a year without problem...It isn't the Platinum version tho. It's the Basic OEM version, and has had the patches run from the Roxio site and (maybe I've just been lucky) it's worked fine. Now Franke, There are Upper and Lower filters in the registry that may be causing the drive not to show up under "My Computer". Randomly when the Roxio SW is removed they will disappear until the filters are deleted. HKEY_LOCAL_MACHINE\System\CurrentControlset\Control\class\{4D36E965-E325-11CE-BFC1-08002BE10318} Both the upper and lower filters can safely be deleted, then restart. The optical drive/drives should reappear then. As always be careful in the registry, and good luck!
