After updating to Mavericks today and iTunes 11.1.2, iTunes is required to be run in 64-bit mode. Now my .m4v files will not play in iTunes: "This movie requires QuickTime, which is not supported by this version of iTunes". I remember a while back I had to set iTunes to run in 32-bit to resolve this, so how do we resolve this now without recoding all my files (~500 movies and TV shows)?
