If you are having trouble finding Chinese content to practice listening with, I found a neat site called tudou.com (土豆 - tǔdòu - which, as far as I can tell, means "potato").
It's basically a Chinese version of youtube, but it looks a lot nicer. When you watch a movie, the layout simulates a theater. I find that a nice touch. And just setting the background to black instead of "youtube white" makes quite a bit of difference in the experience.
I can't navigate the site with any purpose yet because there are too many words I don't know, but it's easy to click around and play some clips in Chinese - some of which are captioned.
I think it's a good learning tool. It's easier than trying to find Chinese clips on youtube, and it streams a heck of a lot better than cctv.com (flash vs. WMV).
