Recently, couple weeks after installing Roxio, I had to reinstall Zune software to get it to recognize my Zune player. A couple days later, it wouldn't recognize my player again, so I totally resync'ed my player ... what a pain, but I got my Zune system talking again. Then today when I tried to burn a CD I just bought, no go on Zune's Burn CD function.
So I backtracked and tested my Roxio burn capability. Waddaya know? Roxio burned the Zune songs I bought (WMV files) to an audio CD. Although it warned some of the content was protected by DRM, Roxio was able to burn the audio CD which plays in a CD player just fine.
If that's all it takes, I can forget about the Zune burner and go with what works.
