Why don't all my videos and songs go on my ipod

Question

I have a regular 30 gig ipod to start. I show on my itunes library that there are 154 videos (all in mp4 format) but only like 15 actually make it to my ipod. I have tried syncing multiple times and it still does not work. Please help! I have had my ipod for a couple of years and have been having this problem since then.

Answer 1

make sure under the movies tab it says sync all movies

Answer 2

may be all ur songs plus videos are over 30gb
