What do Windows error codes actually mean anyway? Is there a

Question

I've got a video that I've been trying to export from Windows Movie Maker, but Windows Media Player and the stock video player keep giving me a 0x00d36b4 error. However, if I import the exported video back into movie maker, it plays just fine. But I'm not looking for a solution -- I posted this because I'm actually curious what Windows' error codes are actually supposed to tell you. How do you decipher them, and is there any useful information to be gleaned from them?
