If your phone is not jailbreak
- use itunes only to sync any music video and photo from pc/mac to iphone.
But if you have already jailbreak
- You can use explorer software such as iphone explorer or ifunbox
to copy anything u want to your iphone but this for expert user only because it will not show any video on your ipod.
-use 3rd party software such as mediamonkey to sync music , video instead of itunes.
