I'm sorry I wasn't clear enough in my previous post - the duplicates that the Recreate M3U script is reporting are not duplicate files/tracks in my library, I verified this by checking the file paths from the dropdown menu in the 4th column of the Recreate M3U script pop-up verification window. Identical title, artist, album, track number, AND file path reported 2 or 3 times, as much as 7 times in the Recreate M3U pop-up verification window. I also verified that I do not have duplicate entries or tracks in my library. So this is not the result of having the same track multiple times in my library - the problem is that the Recreate M3U script is matching the same track file multiple times. Also, I did not have a iPod or iPhone connected at the time, so MM was not matching tracks on an MP3 palyer.
I'm running MM 3.0.5 with a library of over 30,000 tracks. Later today I' plan to install MM 3.0.6 & verify that it works with my iPhone 3G. Once that works, I need to re-install Windows on my PC, it's behaving weirdly in several ways(Outlook hangs often, Explorer crashes, boot takes a long time, virus scanner cant' seem to update itself, etc etc). If a badly behaving Windows environment might explain the script's problems, let me know. When I reinstall MM after the o.s. rebuild, I plan to use Trixmoto's Backup script (love it!!!) to restore my database & settings, after that I'll try the Recreate M3U script again.
