In an answer to another question you wrote "You can disable duplicate detection if you’d like by opening Sharepod preferences and going to the iTunes tab. Just uncheck the box to “detect” if items on the device exist in iTunes"
I have not been able to find where or how to set Sharepod preferences.
To open Sharepod Preferences on a PC, just press Control-comma (on a PC) or click gear menu > Preferences. To open Sharepod Preferences on a Mac, click on Command-comma (on a Mac) or Sharepod menu > Preferences. Then, you’ll find the duplicate detection settings on the iTunes tab. Just uncheck the box to “detect…”.
