I know it must be possible:
But how can i put my vidoes from my phone, digitial camera on my ipod?

and

How can i put flims on there?
Do i have to download a seperate software?

You need software to convert the videos from your phone/camera into a format that the ipod will play, and then add them to your itunes library - the next time you sync your ipod, it'll upload the videos, too.

I use imtoo dvd to ipod converter, but that costs money ( a whopping £8 ). Why not try googling for tutorials and software?
