As has been mentioned, the only way to get the original series as aired, with absolutely no changes at all, is to get the second set with the corrected discs. The recalled set has music substitutions for most scenes that involve jukebox, radio or other incidental music, plus I believe at least two episodes have scenes without any background music at all where there originally was. I hadn't heard about the lip synching issues. It was so easy to exchange the recalled set for the new release and then easy to get the corrected discs for the second release, I can't imagine anyone settling for a compromised version when they don't have to. It's my favorite TV series of all time, so I'm happy I have it in its COMPLETELY UNEDITED form.
