Need iTunes – iPod Help!

So if you saw my last post, I am now doing Flash tutorials for video iPods. But I myself am a total newbie when it comes to iPods, iTunes, etc. I’m having some weird issues that hopefully someone can help me with:

1) Sometimes I add a video with iTunes and it shows up fine in the videos -> movies -> directory. Other times when I undock my iPod it puts all my music AND videos into the music folder and if I try to play a video, all I get is the audio.

2) If I create a site for these tutorials, how can I set it up through iTunes so people can automatically get them? Like I said I’m new to the whole Mac world.

3) Also can anyone who has downloaded the tutorial and watched it comment on the quality and if there were any bugs?

Thanks so much
