I may have found a TEMPORARY fix. It will probably have to be redone as needed, when downloading new software etc.

My problem was that the CD would not auto-run from ANY media player, including iTunes. I tried a multitude of things. It seemed that iTunes and the CD auto-run were fine until I installed Office 2007, then it stopped. It MAY have been due to a restart instead of the actual Office 2007 install, but I'm not certain, because after 2007 install I reloaded iTunes, and it worked until I restarted it. However, after deleting the filter(s) in the registry, the CD auto-ran fine, even after restart. I did get a message saying iTunes files were missing, and that I needed to reinstall iTunes, but so far I have not done so.
Hope this helps, but more than anything I hope Apple reads these forums and realizes they have an unresolved problem that's making a lot of folks very angry! I spent several hours yesterday, and a couple of hours this morning, searching for a permanent fix, but this was the best I could come up with.
