Movies still avail. for osx 10.3.9 without upgrading to itunes 9?

Hello,

I am about to go on a trip, don't want to upgrade to osx 10.4, therefore many of the movies I want to buy tell me I need to upgrade to itunes 9. Are there any movies still avail. to buy if you do not have 10.4? I've seen a few tv shows, etc. but not movies, mostly for my kids.

Thanks!!
