Well, it is possible some files in your media center may have been corrupted after sp1. Is this the first trouble you've had? What kind of computer do you have? My "Roxio" software came preinstalled, all I had to do is return my computer to factory settings. Although, Rhapsody won't re-install. I have to download directly from Rhapsody. (Nero 8 is not for a novice) There's a review between the two software's on-(trusted review.com ) Nero 8 vs Roxio Easy Media Creator-10 You'll lose your Roxio to put in Nero- I was thinking you should try to update what you've got, or re-install. Someone said Nero is faster...... MVP's like Roxio- your choice. You know I'm not sure, I think you own it more or less, if it's been preinstalled- but don't quote me on it.
