iMac won't ever go to sleep on its own

I have a C2D iMac about 3 years old, with 10.6 and all the updates. I have it set to go to sleep after 30 minutes of inactivity. Sometimes at night I will use it to listen to a podcast or watch a TV show. When I do this, it never goes to sleep. It's always still on when I wake up. The display will sleep, but not the computer. I can put the computer to sleep myself through the Apple menu, but it never sleeps due to inactivity.

I'm worried that having the computer on 8 hours a night due to this problem will shorten its lifespan. Does anyone have an idea of what may be causing it? Does it have something to do with webpages being open? I always have Safari open. It's easier to leave pages open than it is to go through dialog boxes and menus to create and delete bookmarks all the time.

I'm pretty new to Mac's to but...

Are you saying that it won't go to sleep while playing the video or music?
I don't think that would be counted as inactivity, have you checked to see if the program you are using to play these podcasts/music have settings to close the program after a certain time?
I'm not sure if you can have the Mac override the program and sleep..
