iPod - iTunes

Last month I wrote about getting a new video iPod. Since then Basia has taken quite a liking to it, so much of a liking I wasn't getting any time to play with my new toy. I suggested that maybe she would like to have one for a Christmas present. No, she says I already have one (pointing to my iPod she's wearing).
So, last week I went out and bought myself a 4GB nano. It was locked up right from the box (or I locked it up myself trying to get my computer to recognize it), anyway, I got it to reset and there've been no problems with either ipod since.
iTunes, on the other hand, seems to be the buggiest program on my pc. No other program crashes as often for me as iTunes. I only have the problem when watching video. Has anyone else had this problem?
