I guess when I tried emplode it wouldn't record on top of the existing unresolved tracks?

As far as I know, it should give you an on-screen option as to whether you want to record again. It says at the top of the screen "Already recorded this CD" and then gives you some choices. If not, it should at least take the CD and then you can go into the "record from CD in tray" menu and go from there.

I hope in the next version of the software there is an option to automatically connect to the internet if there is an unresolved title.

It's there right now, in the Internet Connection Settings menu. Mine is set that way already.

You can also go into that menu and tell it to resolve any existing unresolved tracks from the internet, even if the CD isn't in the drive. This allows you to "resolve later" if you choose not to do so at the time you insert the CD.
