Movies to ipod classic Itunes

Well i suppose nobody had time to answer my previous post, so here again the same question in English this time.

I recently converted all my movies from my camera and i want them to be on my ipod classic. Everything goes well with my ipad, but I can't get them on my ipod. I converted them to MPEG4, so that's right I suppose.

I run Itunes on my macbook...

Idea's? (sorry for my bad English)
