This question may have been answered, but I can't specifically find an answer. My apologies if already answered. To synch my Droid to Mac I bought MissingSync. Several vidoe clips and songs would not sync. And the podcasts were all jumbled, not nicely organized like in iTunes. So I tried doubleTwist. Everything seemed to sync OK, and the podcasts seem better organized. Question is, does each app do their own syncing, and in essence duplicate each others storage? It seems that way. Is there any way to get a single copy of my music library to the Droid, and then have one app or the other point to the library?
