I am trying to download WWDC videos from iTunes U. When I click on "Get" it starts downloading but after the download completes it disappears from iTunes U collection.
I tried to download it from my new MacBook Pro, OSX Lion and iTunes 10.5 .
When I downloaded the same video from my office mac running OSX Snow Leopard 10.6.7 and iTunes 10.4 everything worked.
What could be wrong in this case? Should I wait for new iTunes update?
