As I'm reading it here, @ohrenkino interpreted your mention of "chapter" different than you've meant it. Some file types have the concept of chapter, which refers to the internal structure of the file's metadata. This is not what we're taking about here 
Regarding Windows Media Player: I'm struggling to use this software and really have no idea how people can use this effectively. What I've read here on the forums is, that it can help to remove the files from WMP and re-add them, so that it picks up the tag differences. Also, use ID3v2.3 at "Options > Tags > Mpeg" and save the tags, because WMP still seems to have difficulties in supporting ID3v2.4.
