I really wish I had never updated to ios5. I have had so many syncing problems since I updated. The latest is that I tried to add a mp4 video to my video collection and after I had synced half my music was missing(greyed out), all my photo albums are missing ( the photos are there as a long stream of 4000 photos but the albums are not showing), and I get the message that xxxx items can not be synced, check iTunes for details. i have tried syncing several times and at one stage it said 3100 items could not be synced, the latest is 31 items. I had none of these problems with ios4. Another problem I have with ios5 is that I can no longer use djay to send my music by bluetooth to my Phillips bluetooth dock. The sound cuts out every few seconds, it works fine if I physically dock the iPad to the dock. If only there was a way to revert to ios4( i know there isn't) - i have the same problem with my ios5 iPhone 4.
