If I were you I would just ditch Windows media player for something better, its just too troublesome despite its "with the OS"
I suggest trying out Video Lan Client (AKA VLC player) and or SMplayer or even realplayer but I support VLC and Smplayer more.
Both are adware/spyware free, no stupid 30 day trials, no nagging, they are both $100 free to install and use without any hassle that you get from most software you might find:
Try VLC player first
As for burning software again windows media player should be ditched for that purpose as well.
try out infrarcorder here
