CD/DVD Player Not Working

[Værn]

*RAWR EDIT*
Problem solved. Somehow turned out to be exactly what you said, even though I haven't installed any new CD/DVD software in nearly a year. Just had to delete a single filter from my registry and it was insta-fixed... hooray for 4-year-old threads on random tech forums for telling me exactly where to look ^_^
(Found it almost instantly when I searched for the code 19 error instead of my drive model :P)
