Choppy HD 1080p videos only in itunes

I'm having the same issue. My playback is all choppy. I have a lot of shows in iTunes and I would like the watch them there... where I purchased them. I have live action shows and cartoons. The cartoons I don't have much of an issue with. It's the live actions shows. What is the issue? I just tried one live action show in QuickTime and it works. Still some choppiness, but not like iTunes. At least there it's more playable. I have the current version of iTunes.

Here's what I'm running:

Windows 8.1; AMD E2-2000 APU with Radeon(tm) HD Graphics; 1.75 GHz; 64-bit processor; 4 GB RAM

Got the exact same problem, even tried a few more media players which all played them fine.

Is there a problem with the codec that's shipped with iTunes for windows and is there a way to change the codec used? This problem is sort of bugging me big time since it's playing perfectly everywhere else and I would very much prefer to use iTunes for everything, reason is that I rather use one media hub for everything so if iTunes cant do it then maybe it isnt the solution after all.

Have this problem when playing 1080p videos in iTunes as well as QuickTime Player, havent tried any 720p yet after buying a new computer so cant say if it's choppy as well.

Anyone managed to solve this or have any ideas or any idea how to replace the iTunes codec? I rather not move away from iTunes just because I cant play HD movies when I'm using Windows.

Same issue here too, using itunes 10.7.0.21 telling me that my computer is too slow for playing the video file. This is certainly not the case because the video works in other players and my computer is more than capable of handling it.

GTX 680 Graphics card

Intel Core i5 3.4Ghz

8GB RAM

Windows 7 64-bit

Its a problem with iTunes

Same issue here, using itunes 10.7.0.21

DELL XPS 8500

Intel i7-3770 CPU @ 3.4 GHz

8GB RAM

Windows 7 Home Premium 64-bit Service Pack1

AMD Radeon HD 7570

I have the same issue here. I also tested playing the HD movie with ATV 2 from iTunes library and it worked fine. Only iTunes does not play it.

Same issue here. Newest iTunes, choppy mp4 playback. Plays flawlessly over appleTV and when homesharing to my iPad.

I'm running windows 8, with a core i5 3570K, 8GB of ram. and a radeon HD 7750 video card.

I have the same issue, someone got the solution?

The solution is to not use itunes to play your videos, unless you purchased them through itunes, then you have to.

iTunes is a resourse hog, and unless you have a veryfast computer and graphics card, you will probably have problems. VLC is free, and will play any format, and uses very little memory.

I monitored my PC during video reproduction only 30% of CPU capacity was consumed during peak and only 50% of available RAM memory.

My desktop is a Intel 3930k OC 4.5Ghz, 32GB RAM, gtx 680 graphicsboard and it's lagging (computer is basicly idling when checking stats).

My MacBook Pro is a Core2duo 2.4Gz, 8GB RAM, Geforce 320M graphicsboard and no lag.

Definitely not about resources, still suspect it's the way the codecs working with acceleration but I'm in no way good at the nitty gritty of video acceleration or codecs. Still hoping for this to get fixed for windows so I can use iTunes for everything, thankfully I watch most things through the AppleTV but it's sort of annoying the times I do want to watch something on the computer or check something in a movie.

Let's hope that the new itunes version 11 end of November fixes some bugs

I have installed iTunes 11.0.0.163 and issues persists. What a shame. Please if anybody found a workaround share it.

Thanks

The same here. Nothing has been fixed in the 11 version. The same mistakes as ever. Jerky HD videos and more. new happened. Itunes, the connection between ATV3 and Itunes not be sustained. After 15 min (my hibernate settings) of the PC goes into hibernation. The older versions Iunes understood the PC to stay awake as long as films or music is played.

I am glad to see I am not the only one having this issue with 1080p. I have read about apparent solutions but nothing has worked. 720 has no issues when imported into itunes, but 1080 appears choppy, however wmp and vlc play smoothly without issue.
