Hi Aron,
You really have to look at the text file included with each show, to make sure that you have the correct version of Mission Impossible (or other music) for a particular show. For example, sometimes songs are released on several albums which have different "start times". The text file for each show can also be accessed after you load a show. Just click on the menu called "Edit", and then "Show name and description".
Also, at the last SELEM, I seem to recall a mysterious CD floating around with Pangolin music. It's just a guess, but probably the shows included with the Pangolin installation CD might also magically be perfectly synchronized to songs found on the mysterious CD...
Again, just a guess
Best regards,
William Benner
