10.5: Quit iTunes to see file info changes in Front Row System 10.5
If you edit the info of files in iTunes and then launch Front Row while iTunes is still running, you will not see the changes you have just made. To fix this, quit iTunes after editing file info (you can relaunch iTunes straight away if you like; it makes no difference). When Front Row is next launched, the info will have been updated.

I don't know why this happens (I'd like to though), but I believe it is because Front Row is now an Application in 10.5. This is on OS X 10.5.2 with iTunes 7.6.1 (9), with "Keep iTunes Music folder organized" checked.

I don't know about iTunes file management, but I have found that when I add something to, for example, ~/Movies while Front Row is running, I have to back out to the top menu in Front Row and then navigate back in to see the new files.

Front Row always was an application. Anything you can do on your computer is an application. If you're talking about the fact that there's now an icon for Front Row, all that does is give you another way to invoke Front Row. If you get info on that "application", you'll see it's only about 376 KB, which is obviously too small to contain any of the actual functional code. All it is is a shortcut. It's there mainly for people using it on systems that didn't ship with an Apple Remote. You'll notice there are also "applications" for Spaces and Exposť, but again, these are just a convenience. Exposť doesn't work any differently than it did before; the icon just gives you another way to invoke it.

The only reason I can imagine needing to quit iTunes for changes to show up in other programs is if they were reading the iTunes Music Library file instead of simply querying iTunes directly, but it wouldn't make any sense to do that, because iTunes has always made it very easy for other applications to access its database. Even simple AppleScripts can easily get the current list of playlists and songs.

So unless Apple did something really dumb when developing Front Row 2.0, there shouldn't be any need to quit and relaunch iTunes for changes to show up in Front Row. Try returning to the top-level menu in Front Row and going back into Music.

I believe what the original post was referring to is that under Leopard, Front Row now plays music from the iTunes library natively, whereas under Tiger, Front Row simply controlled iTunes (if you started to play music in Front Row, iTunes would actually open in the background).

In my recent experiences, this applies to the AppleTV as well. I keep most of my TV shows on my Mac and just stream them to my AppleTV, and I've found that when I add new episodes, they sometimes show up eventually on the AppleTV. However, if I just quit iTunes and immediately relaunch it, the list updates.

I'm using the AppleTV 2.0 software, so I'm not sure if the same is true for the original... though I don't believe the old software let you view your synced and streamed content in one place without having to switch sources.

I'm pretty sure it happens as a result of the architecture. All of the inter-application interaction with the media libraries uses the .xml files generated by iphoto, itunes, etc. Inside the iTunes folder, you'll find an itunes library, and an itunes library.xml . Chances are the xml is generated only when itunes quits.

Yes, I'd bet that this is exactly the cause. The XML gets generated from iTunes when iTunes exits, and FrontRow (and other apps) read their info from that XML file.

this is not the sig you`re looking for.

I believe this is because iTunes writes changes to a temp file and updates the main database on quit.

I think you've got it.

This XML file is specifically there so that third party applications can read it, I believe. But iTunes itself uses a binary database that is much more efficient for reading and write, and so the text-based XML file is updated only when quitting.

Shame that there is no public API a la Address Book.

10.5: Quit iTunes to see file info changes in Front Row
Authored by: leamanc on Mar 12, '08 11:25:04AM

I have run into things like this only since upgrading to 10.5 (hence the 10.5-only status of this hint, I suppose). Others posting here mentioned backing out to the top-most Front Row menu to see the changes. Most of the time, I have to back all the way out of Front Row to the desktop to see any changes (new movies or music added, etc.).

I can't say for sure, but I think Front Row has some sort of process that runs periodically to check for updates. I've noticed that if I wait for a few minutes, often my updated files are there without having to go entirely out of Front Row.
