Exporting from iMovie to video iPod won't work

Question

Hello everybody,
I am just fooling around with the new iPod my wife gave me for my birthday.
I am trying to get a movie I just finished into my iPod.
As my program is in German, I hope I'll use the correct English words .
In "File" there is the button "Send"; when You choose "Quicktime" and "own settings" there'll be a window "export as...", where You choose "film --> iPod (320*240)" and push the button.
After rendering I dragged the outcome into iTunes, and there from the bibliotheque to the iPod. After that I keep getting the error message (roughly) that my film could not be copied, as the iPod can't play back films like that. There is a link where they promise You further information, but that leads to nowhere.
The film plays back from the iTunes bibliotheque without problem, it's suffix is *.m4v.
Has anybody got a solution (or an idea, at least)?

Are you using this article?

(Unfortunately it's available only in English, French
and Japanese.)
Thanks for the quick reply.
I didn't know this article, but that's exactly what I did; I just used the greek word "bibliotheque" instead of the latin "library" .
And the suffix of the file after rendering is *.m4v as in the above mentioned article.
Still it won't work.
What can be wrong?
Greetings
