iTunes 10.1.1 is available in Software Update
iTunes 10.1.1 is ready for your approval via Software Update. This looks like a minor bug fix update with no new features. Here are the fixes:
Addresses an issue where some music videos might not play on Macs with NVIDIA GeForce 9400 or 9600 graphics
Fixes an issue where iTunes may unexpectedly quit when deleting a playlist that has the iTunes Sidebar showing
Fixes an issue where iTunes may unexpectedly quit when connecting an iPod to a PowerPC equipped Mac
Addresses an issue where some music videos might not sync to an iPod, iPhone or iPad
Note: A number of commenters have reported that this update doesn't work. I tried it myself and after applying the update, see what I got after the break.
The solution is to download the whole 90.5MB file from the Apple site -- that should set you up with a working copy of 10.1.1.
