Mavericks & iTunes 11.1.2 with .m4v files "This movie requires QuickTime, which is not supported by this version of iTunes."

You should have posted that in another, more appropriate thread. It's completely irrelevant to my topic. 😐

The only thing I can think, iTunes operates in 64-bit, but there's a limitation for importing some files that require iTunes to be operating in 32-bit mode. You can "get info" on the iTunes app. Check the "open in 32 bit mode" and restart. See if that works.

If it does work, but you don't want to open iTunes in 32 bit all the time, you can dust off Quicktime, export the file from QT using "passthrough" options. It rewrites the file container without compressing the video and usually solves the problem. If this is the probelm.

If you read my original post, you will see clearly that I stated iTunes is NOW REQUIRED to be run in 64-bit mode with iTunes 11.1.2 and Mavericks. Your suggestion is moot.

Just so there's no confusion!!

Unfortunately this solution is rather a final solution and not verified so far AND wrong MacOSX-Version....

After reading the discussion linked by iamborg (nice Star Trek reference in name 😀 ) I tried deleting one of my troubled files and re-added it (a tv show episode encoded in .m4v, but .mov files have the same issue), and it finally worked properly in iTunes 11.1.2. So it does have something to do with how the upgrade(s) (either iTunes 11.1.x or Mavericks or both) treats files located on external drives (where all my video media is located). At least I don't have to re-encode ALL my video files for iTunes, and this is no longer a 32-bit vs 64-bit version issue. I suspect this is why moving files to your internal HD works as someone else suggested. It's not about where they are located, it's about how the iTunes library is updated after the upgrade(s). Almost all my movies and TV shows are affected.

So for me the work around would be removing all the troubled files from iTunes library and re-adding them (keeping them in their original location on the external drives). This means hours and hours of work since this process does not keep any of the information under the Get Info -> Video tab (Show, Season Number, Episode ID, Episode Number and Description are all blank after removing and re-adding them). It also sets the Media Kind back to Home Video and not TV Show since they are my own rips from my purchased DVDs (which is an easy fix by selecting all and changing them to TV Show in one full swoop).

I did look and see that the " iTunes Library.xml " file is showing the correct information for the files that don't play, but removing and re-adding them does change the Track ID, Date Added, and omits all the show info (Show, Season Number, Episode ID, Episode Number and Description) settings until it is manually re-added to the Video tab in Get Info. Playback settings are also lost when a file is removed and re-added back to iTunes (playback position, play counts, ratings...). Losing play counts and other miscellaneous data such as ratings, the skip when shuffling setting if you unchecked it, and playback positions WILL affect smart playlists you created in the past. Basically everything under the Options tab in Get Info was reset to default for me after removing and re-adding any affected file(s). 😟

**Keep in mind that files that don't play after this issue will probably lose their artwork in iTunes after you get info on the broken files until you remove and re-add them to iTunes. Don't worry, the embedded artwork is still there and can be seen in Finder and returns after they are re-added back to iTunes.**

I now wonder if there's a way to force iTunes to rescan my entire library without losing play counts and other options so I won't have to do thousands of manual tag edits all over again and lose my smart playlists. Every major iTunes update breaks something for many of us. UGH!!

I tried playing the video podcast Mos Speedrun on three different machins: Mavericks 64-bit with latest iTunes, Windows 8.1 64-bit with latest iTunes, and Windows 7 32-bit with latest iTunes, and they all failed to play this podcast. It won't even download on any of the machines if I try subscribing to it. This podcast might be corrupt since I can't even subscribe on any platform. Have you tried another video podcast? I have dozens of video podcasts I subscribe to and they play fine.
