I have not looked at iTunes4 to find out whether the directories are handled in different ways when compared to earlier versions of itunes. We do have .mov streaming files on our servers and we have .mp3/iTune files on a station that synchronizes a pool of ipods that we loan out to students on weekends or for trips. The conversion of our existing files was simple - we used Cleaneer for that. Establishing the directories within iTunes - to make them look similar to the directories on the server - was a real pain, to say it mildly. MP3 files, by the way, do not really stream. It is very easy to download them. Otmar
