Nano not syncing

The following information has come directly from the apple support web site.

Adding Content Automatically or Manually
There are two ways to add content to iPod nano: ? Automatic syncing: When you connect iPod nano to your computer, iPod nano is automatically updated to match the items in your iTunes library. You can sync all your songs, playlists, videos, and podcasts, or, if your entire iTunes library doesn’t fit on iPod nano, you can sync only selected items. You can sync iPod nano automatically with only one computer at a time. ? Manually managing iPod nano: When you connect iPod nano, you can drag items individually to iPod nano and delete them individually from iPod nano. You can add songs from more than one computer without erasing songs from iPod nano. When you manage music yourself, you must always eject iPod nano from iTunes before you disconnect it.

The following URL will bring you to the iPod Nano manual. For more information on setting up you iPod see chapter 2: Setting up iPod Nano

hi, buddy
First, you need to ensure ur video is in ipod-friendly format MPEG4(MP4), M4V... if not, you can use iTunes to convert them...

Next, use iTunes to sync them to ur iPod. If you wanna more convenient, you could download this iPod manager tool - Daniusoft iPod transfer :

1. Backup videos/songs from computer to iPod directly ;
2. Transfer iPod files to computer smoothly ;
3. Transfer iPod video/music to iTunes .

...

Test the songs that are not playing on the iPod in iTunes and see if the original file is still playable on iTunes if the song still plays re-sync your iPod could be when iTunes copied the song it must have failed or timed out, if that fails re-syncing try restoring you iPod Nano i have had this problem before and I just re-synced and it worked fine!

only 3rd generation iPod nanos can play video, and the video must be mp4, you can use itunes to sync video to ipod nano, just follow those steps:
1. Open iTunes and click "File" to add your videos to iTunes library.
2. plug in your iPod Nano to computer, then iTunes will detect your iPod Nano as a device.
3. Select your iPod Nano device on the left panel of iTunes, click "Movies" tab, check the videos you want to sync and click "Apply"

Use iTunes 8 to sync or delete songs, photos, etc. Just connect the iPod to computer, download iTunes 8 from the internet, open iTunes 8, and then double-click on the icon of the iPod Nano to Sync files to your Nano.
The manual for the iPod Nano can be found at www.apple.com/support

What seems to have happened is that either iTunes or the iPod folder has become corrupt. To solve this, download the very latest version of iTunes, install it, connect your iPod. If it wants to update the software on your iPod do this. Then on the main ipod page on iTunes click the button that says Restore. Choose the bottom most option if given any then go ahead and restore. You should now be able to sync as normal.

All the best

make sure on itunes it says sync all selected songs(make sure all songs you want to download are selected)then try to sync it again if thats not your problem it could be a bad i pod

you won't remove whats there unless you sync your ipod to another computer with itunes, use iTunes for all your music sync. Just copy your other music to it, by dragging to an open iTunes window. Add the new content to your playlist, or via settings in itunes (with your IPod connected) sync. :)
