Choppy playback for iTunes movies

HI Facepalmmonkey,

I had this exact problem after renting an HD film from itunes.

I used itunes NOT quicktime to view the film

I am not very computer savvy however I found reducing my screen resolution to the lowest option (800x600) solved the problem.

I have a rather basic 5-6 year old computer so I am unsure if it was just my laptop at fault and not itunes.

The only drawback is that reducing the screen resolution also reduced the picture size.

However this was better than watching a very slow and choopy film for 2 hours.

Hope this is some help?

I Have had trouble playing iTunes movies and shows since I bought an Asus laptop with windows 8 in 2014. I had since upgraded to windows 10 but continued to have the same trouble. I've Followed several of the articles in this post and the one which I believe worked best was syncing the audio playback settings to 24 bit and 48k In iTunes, QuickTime and BoTh audio adaptors installed in my laptop, one is the Realtek HD and the other is integrated with the HDMI. I have my system set to use the Realtek HD by default.

one final note, prior to doing this, I was monitoring performance and saw that the hard drive and memory usage were nearly maxed out while trying to watch an hd movie. I killed iTunes and let the system settle down before retrying, I suspect windows was trying to install updates or something, but after that and performing the changes, movie was golden.

This completely fixed the issue I had with itunes movies being all glitchy after the itunes upgrade. Also, I have a Samsung laptop, not a Mac. Thank you!!!

I had choppy movie playback, these are iTunes digital copies that came with Blu-rays. I have a Windows 7 64 bit computer. I play movies via HDMI on my 60" panasonic TV.I fixed it by going into QuickTime and changing video playback from DirectX to Safe Mode under QuickTime preferences..

This. Is. Still. Happening.

Windows 7 64 bit

GeForce GTX 670

Intel i5-3570, 3.4 GHz

Just to clarify: changing the QT settings will affect iTunes playback?

Depending on the video format you might have more joy if you install iTunes for Windows (64-bit - for older video cards) and QuickTime for Windows. If you installed iTunes using the iTunes6464setup.exe then it probably won't hand off to QuickTime.

I am running Windows 10 and had problem with choppy playback. As suggested by zerostatetechnologies, I set both my windows settings to 24 bit and 44 Hz as well as iTunes and this cleared up the problem.
