I post this once above but it got swarmed with the larger xml related issue that prevented syncing at all. Not complaining, just wanted to revisit this other issue now that folks are mostly able to get their syncing started. I'm pretty sure this, too, is an xml related issue. To that end, can anyone point to where iTunes is getting it's list of iPhoto Events and Albums? **
I believe we are all experiencing variants of the same issue.
Here is mine and I'd ask if others are seeing this specific issue as well.
With an iOS device attached, and looking at the photos tab, I see a number of Events with questionable names that seem to be old data from somewhere. They look like the name of test events I may have made and delted over the years. Regardless...they are are empty.
I then checked the Advanced tab within iTunes and used the share photos option I use to stream photos to my TV and the same empty Events are there too.
These first two are annoying...and now comes the really troubling part.
For the Events that are not blank and look like the ones in my iPhoto library, many of these events are not reporting the same number of photos as does iPhoto. For example, an event named "Beach" in iphoto consists of 100 photos, but that same event when selected within iTunes only has 85 photos in it. When iTunes sync'ed the first time it reported XXX items could not be sync'ed check iTunes. That error message has not yet reoccurred but I can confirm that only the 85 photos sync'ed not the 100 that are present on my iPhoto 9.4 library.
If I drag the entire contents of that same 100 photo event to the desktop and then drag it back into iPhoto, iTunes will then recognize it as containing the full 100 photos. But...of course you lose all tags, face data, etc.
I'm not yet prepared to do this major surgery, but does anyone have other ideas?
One additional thing I noted...remember that there were always more pictures in the iPhoto Event than in the iTunes list for that Event. Well, I noted that all the images that were missing from iTunes and thus my iOS device, pretty much sucked. Why is that important? It seems like they might have been pictures I previously deleted but that iPhoto still has in the Event even though iTunes doesn't "see" them.
Conversely, it seems like iTunes is seeing old Events that I had long since deleted from previous incarnations of iPhoto.
Anyway...if you have a moment check out your iTunes list of Events and Albums to see if 1) there are extraneous Events listed there and 2) if the number of pictures in those events matches the same number reported by iPhoto.
