Quicktime and Roxio Jam

Good Day xiph Crew,

Your unique app/utility is priceless. I wish I had more knowledge with these softwares. I was wondering how I could get Quicktime to acknowledge the .ogg files besides for using the file open option. How can I use .ogg files in Roxio Jam 5 (more stable than 6)? Thank you for your time and talent. -Respect
