Is there any way in XP Home to schedule
the computer to automatically shut down
at a specified time?

For instance, if playing a Radio program and
I want it to shut down by itself at a certain time?

Thanks!

Check some of these out (Slawdog and Poweroff look good)

Another good one is DHshutdown you can find it here.
