Solved the earlier problem - Vista would not recognize CD drive. Just jiggled drive and screwed it back down; works fine now.
Current problem - the burner no longer burns music w iTunes. It burns OK with Windows software but not iTunes. I followed the directions to uninstall iTunes including all the folders plus emptying Recycle Bin. When I try to burn, I get a message that something from iTunes did not load and I need to reinstall. Reinstalled twice and continue to get same msg.
Then saw a note that said try an older version of iTunes because some of the newer versions work OK with Macs but still have PC bugs. Installed itunes 4.2 version = very old. Still no burn.
That's where I am now. It burns fine with Windows but iTunes will not burn. Plus I lost all my iTunes playlists.

Help.
