Q: Trying to play a movie purchased in iTunes and just freezes

Hey there adobeman,

I see that you are running into some issues with your attempts to play The Big Lebowski, and your iTunes is being very un-Dude about the whole thing. First, I would like to suggest that you test this behavior in Safe Mode:

OS X El Capitan: Start up in safe mode

If this issue appears with any purchased video in iTunes, you may need to reinstall iTunes by reinstalling OS X:

If this only happens with The Big Lebowski, you may want to report the issue: 

Report a problem with an item purchased from the iTunes Store, App Store, Mac App Store, or iBooks Store - Apple Support

https://support.apple.com/en-us/HT204084

If reporting this issue does become necessary, I can assure you that we’ll get some boys down at the crime lab on the issue immediately; we’ll even make them work in shifts!

"Stay out of Malibu, deadbeat!"
