Sync multiple iTunes libraries on one ATV

Is it possible to sync the itunes libraries from my two macs onto one appleTV? The libraries are unique.
When I try to switch source to sync....ATV says I will replace the contents from the previous sync with the contents of the other mac.

I don't have an ATV yet (should be arriving any day now), so I can't test this, but at the very least you should be able to stream from two different iTunes libraries on the same computer. This article mentions doing it:
http://docs.info.apple.com/article.html?artnum=305287
Apparently when there are multiple logins with multiple instances of iTunes running on the same machine, they use additional TCP ports that would normally get blocked by the firewall, if it's turned on. Maybe you've got the firewall turned on, and it's smart enough to open a hole for the standard iTunes port (3689) but not the extra holes for additional users (49152 and above).

Have multiple iTunes libraries on one machine?

Hi,
I want to have multiple iTunes libraries on one machine (with two different hard drives, internal fore mp3s and external for AAC files). One library is composed of mp3s for an iPod, I want the other library to have AAC audio files for burning CDs. I would rather the libraries not be mixed.
I have read the article (#301748) for migrating an iTunes library and am preparing to migrate one of the libraries on to a external hard drive.
I have read about using Libra to maintain two different libraries on one machine. I was wondering if anyone does this and if they have encountered any problems? Is there a better solution?
Thank you,
TPK

It's one thing to want two music libraries on one machine and another to want two music libraries on one user account. For the latter, here's what I've done.
I created folders in my iTunes folder called, say, Main Library Folder and Second Library Folder. (These could be anywhere you find convenient.) I dragged my regular iTunes Library file into the Main Library Folder. Then I opened iTunes and created my second music library. When I finished that, I closed iTunes and dragged the just-created iTunes Library file into the Second Library Folder.
If I want to use my main iTunes library, before opening iTunes I drag an alias (Cmmd-Option-drag) of the iTunes Library file from the Main Library Folder into the iTunes folder. Then, when I open iTunes, iTunes reads my main library file. And of course, it works the same way for the second library.
Of course, you could just shuffle the actual library files into position in the iTunes folder from their holding areas, but I strongly preferred to get myself into the habit of relying on aliases, so I could leave the actual library file alone in their respective folders. You most definitely would not want to accidentally overwrite one of your iTunes Library files.
I'm sure one of the shareware products would do a more elegant job, but this just shows you that it's not a difficult process.
The alternative is to set up separate user accounts to access different libraries on the same machine. This has real benefits and, to me, should be the first option one considers. It's easier on the brain, as it sticks to iTunes' one-user-one-library model, and there's absolutely no risk of getting libraries confused. Fast User Switching on the Mac makes going back and forth between accounts easy. But if you really want to avoid using different accounts, and it's only you that has to keep things straight, the approach of jumping back and forth between different libraries in the same user account should be OK.

Sync multiple iTunes libraries with iPod?

How do I sync several iTunes libraries (selectable by holding down ALT while starting iTunes) with my iPod Touch (4th generation)?
With limited hard drive space on my Powerbook I've chosen to create an iTunes library which more or less just contains podcasts and internet radio stations etc. and use an external drive for another library which contains all my music.
I was hoping I could switch between the different libraries and have my iPod sync to both of them, but alas I get a message when switching over to the "music" library that my iPod "belongs to" another library and that if I choose to use the current one everything will be erased and overwritten.
So how do I prevent this from happening while allowing me to add music from the second library?

I'm not sure if I've got it right but I've played around a bit after reading the above and come to the conclusion that I first need to check (turn on) the "Manually manage music and videos" (and most likely "Open Itunes when this iPod is connected") options in iTunes when I click on my iPod icon on the left column.
But much to my surprise I can still have iTunes automatically (or so it seems) sync my podcasts which makes things a whole lot easier than doing that manually for each podcast update!
For everything else (music, videos, PDF files/books/audiobooks, iTunes U, Ringtones etc.) I will need to manually drag and drop over to the iPod. To make things easier I created a playlist folder named "Manually transfer to iPod" with various playlists inside (just to make it easier to see what my iPod contains from that particular library and to organize things neatly).
And instead of dragging the items from each playlist over to the iPod I simply select the folder, then drag all the items on the right hand side (contents) over to the iPod.
I haven't tried switching libraries yet, but I assume I'll be able to add media from there as well without any problems.
Was this what you meant?

HT3819 If there are multiple iTunes libraries on one computer, will I be able to only sync my own?

I have a shared computer where my iTunes is at because until now I didn't have the right memory or speed to have iTunes on my previous laptops. I just want to make sure that if I use Home Sharing that I will only be able to sync my library to my laptop, and not my brothers as well.

Sync your library to your laptop from where?
Wiht Home Sharing enabled, you will be able to see all other libraries opened ont eh same network and authorized for Home Sharing with the same account.

Multiple iTunes Libraries on one computer?

I'm a newbie and have what is probably a very simple question, but I'm confused. Both my boyfriend and I have iPods. What we're doing now is he's got his iTunes library on the laptop (syncing and charging on the laptop), and I have mine on the desktop (syncing and charging on the desktop).
We're going on vacation and we would both like access to our libraries on the laptop while on vacation. Can you maintain two libraries on a single computer? How do I manage two different iPods on one computer?
Thanks

How do I sync multiple iTunes libraries on the same PC?

I have a desktop at home running Windows XP Pro. I have my own log-in and my wife has her log-in. We both use iTunes. We both have iTunes accounts. How can we sync our libraries such that we have one (1) shared repository?

You can have identical libraries (contents, playlists and related information) if you set each user's account to reference the same .itl file.
Have a look at this article in the Apple Knowledge Base for details on how to do so.
By using the Choose Library option and linking the accounts to the same .itl file, the libraries will be the same and changes made to one will be reflected in the others.
If you don't want completely identical Libraries but just access to the same files to build separate Libraries with, see this article .

Multiple iTunes Libraries on single Mac

I have somehow managed to create libraries of music/podcasts/videos in 5 different places on my iMac. I would like to consolidate all of them into one spot that can be shared by all accounts. Is there a way to merge them easily, that is without copying song by song or rewriting the entire library, potentially losing some files that are more current? For example, I have 3 folders of the Killers, only 1 of which has all downloaded songs. Thanks.

If you want to do it that way, each person should have their own computer login which will give each person their own iTunes library.
This would be far easier than using multiple iTunes libraries in one computer login.
To do different content on each device, select the device in iTUnes (menu View > Show sidebar), click the tabs acroos top and select what you want to sync to that device. Do the saem for all devices.

Repair itunes library (damaged) file. Multiple iTunes libraries on an external harddrive. All libraries have been working fine. Do some "housecleaning" on a one of the large libraries 296GB. iTunes quit and now has damaged file. 296 GB still on HD.

The duplication is unnecessary. Exporting creates a duplicate of the file. So now you'll have a duplicate of a duplicate. Exporting is not "working on" a file.
No it's not merging, it's exporting from one to the Finder and into another. No matter what lose something. If you export the Original you leave behind all the work you've done in iPhoto. If you export anything else, you lose the non-destructive editing and the ability to revert to the original. With merging you preserve that work. Yes, you can trash the old Library when you have completed the manoevre but no it's not the same thing as merging.
This User Tip
https://discussions.apple.com/docs/DOC-4921
has details of the options in the Export dialogue. But in brief:
Current gets you the iPhoto Preview, used for sharing via media browsers. It's a jpg, medium quality missing metadata. Original gets the file you imported, unchanged and then you can export different version of the current version at different qualities. If you choose to export anything except the Original you do not get a Raw. There's no such thing as an "edited Raw", and you lose the connection between the original and the exported version. That means you've taken a non-destructive workflow and turned it into a destructive one.
The Tiff will certainly be higher qulaity and less likely to suffer generational loss in future editing but the file sizes are vast, often more than 10 times the size of the jpeg.
Put it this way, it would be cheaper to buy Library Manager than the disk you'll need to contain all the Tiffs. Unless you plan on a lot of editing, I'd go for a high quality jpeg as a reasonable compromise.
To be clear:
So, I guess my new question is, how can I edit the Raw image and keep it in a RAW format that IPhoto recognizes so that I can reprocess without any loss at a future time, or is it that once you edit a RAW image, then it is no longer a RAW image?
Once you edit a Raw it can no longer be a Raw. End of.

Have created multiple itunes libraries but when asked to choose a particular one only a single library shows up???

Have created multiple itunes libraries but when asked to choose a particular one only a single library shows up???

Unless you or your software moved or deleted the files from iTunes on your PC, they're still there. Time to go hunting. I don't know where iTunes stores its files on a default installation of a Windows Vista box, but I'd look in your documents folder for something containing "music" in its title. Before you do *anything* to or with the folder, copy it to a safe location. That way if something you're doing messes it up, you've got clean files with which you can work. Make sure you can see all the files in Windows Exploder by first checking your folders settings. By default Windows often hides important system files.

Multiple iTunes Libraries on same computer?

Hi,
My wife, daughter, and I all have ipods, each uses a different computer, my wife and I each use our laptops, and daughter uses the home desktop. Recently, the desktop has crashed and looks like we might need to re-format the drive (i.e. lose everything) and re-install Windows XP. She's got all her music on her iPod but unfortunately, no back up on a CD or DVD. Is there some way to re-create a new library for her from her iPod on to either of our laptops without causing conflicts with our existing iTunes libraries which are totally different. I.E. will the "sync" function work to recreate a library on a hard drive vs. going the other way around as usual.
Any help would be greatly appreciated.

To create or access a second (or more) library, hold down the Shift key in Windows when launching iTunes. In the resulting dialogue you will get the option to create a new library or navigate to the other Library.
Note: You can only have one Library open at a time and iTunes will default to the last library opened if you don't use the keyboard command to choose one. The new library will be empty until you add content to it. To get back to your original library you need to close iTunes and open it again while holding down the shift key, this time choose to open an existing library and navigate to its location: Using multiple iTunes libraries -Windows
iTunes will only let you copy your purchases directly from an iPod to the computer, you'll find details in this article: Copying iTunes Store purchases from your iPod or iPhone to a computer
For everything else (music from CDs, other downloads and including iTunes purchases) there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod. You'll find that they have varying degrees of functionality and some will transfer movies, videos, photos, podcasts and games as well. You can read reviews and comparisons of some of them here:

Multiple iTunes Libraries?

Is there anyway you can have multiple libraries (not playlists) for different iPods on the same computer? We don't want our music to mix...how can I fix this?

The new library will be empty until you add content to it. To get back to your original library you need to close iTunes and open it again while holding down the shift key, this time choose to open an existing library and navigate to its location. Multiple libraries can prove tricky when using multiple iPods, if you don't use the keyboard command you can risk syncing to the wrong library: Using multiple iTunes libraries -Windows
Another option is to create a separate Windows account for each person on your PC. Different user accounts by definition would give you completely separate libraries. Each account has it's own iTunes folder, Library and iTunes Music folder and you load it with CDs etc just as you did with your original one. The iPod can be set to update however the owner chooses, sync all, manual or sync specific playlists.
Apart from these methods there are several other ways to use two or more iPods with one computer, have a look at this help page for all the suggestions and choose the method that suits you best: How to use multiple iPods with one computer

How do I consolidate multiple Itunes folders on one computer?

I had a mishap with my external hard drive (I didn't know how to use it properly..yup USER ERROR!) so I have three different Itunes folders intertwined in my music folders with different previous Itunes libraries. I made a backup of the entire music mess on a flash drive, have a new computer and finally an ipod to put my music on...
Can someone give me some detailed steps to be able to consolidate all of my many Itunes libraries and let me know how I can access the music in my previous Itunes libraries? I want to make sure that I still have the rights to the music that I purchased in the past. I had some music in the Itunes cloud which is great but not nearly all of it...DRATS!
I found some steps to consolidate music from different computers onto one but I'm not sure that the same steps apply to my situation. Here are the links that I was looking at in eHow: http://www.ehow.com/how_5704389_consolidate-multiple-itunes-libraries.html and http://www.ehow.com/how_8149083_can-itunes-libraries-two-computers.html.
Thanks so much in advance!

Set up multiple iTunes accounts on one computer?

I bought each of my two daughters their own iPods for Christmas, and when I set them up, I used my iTunes account login for both of them. It has become an issue sharing my account on their devices, because all of my information comes up on their iPods (like my messages). How can I set up new accounts for each of them, since I only have one computer? I want each of them to have their own iTunes accounts so they can stop using mine. Please help!!!
