Itunes crashes during sync

Question

Just about every time I modify playlists and try to sync to either my Touch or Nano I end up spending HOURS trying to determine which new selection causes the sync process to crash. I end up doing binary searches by dividing the playlist in half, then in half again and again until I find the troublemaker, but I must be missing something. There must be a better way.
The problem selection always plays just fine in Itunes on the desktop system.
What am I stupidly overlooking?
Thanks!

Nombre del módulo con errores: CoreAudioToolbox.dll
Versión del módulo con errores: 7.9.4.0
With your particular one, Christian, there's a bug with 10.1.0.54 that is causing "iTunes has stopped working messages" (citing CoreAudioToolbox.dll in the Problem Reports for the error) for some folks when importing CDs with the AAC encoding, adding/converting files to AAC, and in some cases syncing devices.
Short of rolling back your iTunes to 10.0.1.22 and your Apple Application Support to 1.3.2 (CoreAudioToolbox.dll is kept in the Apple Application Support program files), there's a few possible workarounds.
(1) Change your importing prefs to use a different encoding (won't help with the device syncing variation though).
(2) Replace your CoreAudioToolbox.dll version 7.9.4.0 with a 7.9.3.0 as per:

(3) Or, replace your CoreAudioToolbox.dll version 7.9.4.0 with a shadow copy of a 7.9.3.0 as per:

(2 and 3 do help with the device-syncing variation.)
