I have a hard time adding music or videos to my ipod.

Install iTunes
Before you connect your iPod shuffle to your Mac or PC computer or use it, you must install the latest iTunes software.
2. Connect and Set Up your iPod shuffle Charge your battery by connecting it to an Apple iPod Power Adapter or connect your iPod to a high-power USB port —one that's located directly on your computer—to ensure that your computer charges your iPod battery. (If your computer doesn't seem to recognize your connected iPod , wait about 30 minutes to allow the iPod battery to charge before going further.)

• Charging your iPod battery through a computer or optional power adapter

3. Fill your iPod shuffle and iTunes with Music Once you finish the set up, iTunes will open. It will then either:

• Automatically start filling your iPod with music from your iTunes library (if you set iTunes to automatically update your iPod)

OR

• Allow you to pick and choose what music, audiobooks, and podcasts to add, if you opted to manually manage music on your iPod.

To manually add content, simply drag any file from your iTunes library or playlist to your iPod icon in the iTunes Source list. If you're using iTunes for the very first time, you'll need to add some music to iTunes first, such as songs from your own CDs or music already on your hard drive.

• Adding my music to iTunes
• Adding my iTunes music to my iPod
• Using your iPod as a disk drive for music and other files.
  Note: Syncing music to iPod is a one way street. You cannot copy music from an iPod to a computer unless you enable your iPod as a hard disk first and then copy music files to its disk volume.

4. Disconnect your iPod shuffle Once you've got your music, audiobooks, and other files on your iPod, you're ready to enjoy it.

• If you see an “OK to Disconnect” message on your iPod, simply disconnect it from your computer.
• If you see a “Do Not Disconnect” message, click the eject icon that appears next to your iPod icon in the iTunes Source list and then disconnect your iPod from your computer when you see the “OK to Disconnect” message.
• Disconnecting my iPod shuffle

Hi this is what you do restore the ipod.

Try it on another computer and if it happens its the ipod. Or try restalling itunes with the lates version (7.7.1)
If that doesnt work try using a different program for your ipod eg Jriver media center

Take it to an Apple store in your area and find out if the hard drive crashed on it.

They usually do it for free in there.

Thow it off

i dont really know the solution for this, maybe the computer you have needs a driver to support the ipod but im not sure, i think you should call apple or get help from place of purchase
