Greetings all.


Bit of a mystery here.


I have a Late 2009 iMac that I occasionally use Win7 on via Boot Camp for gaming.


I have iTunes installed so I can watch Movies/TV Shows from my library (served via iTunes running on 2012 i7 Mac Mini).


When playing any video in Windows 7 with iTunes (SD/HD), it stutters, skips and eventually stalls.


The curious issue is when booted into OS X, I can play the same video in iTunes with no problem.


I have attempted the fix in the KB article related to iTunes/Windows 7 video playback.


(disable Direct3D accel/Disable DirectX in QuickTime)


The iMac specs are:

i7, 16GB RAM, 2TB HDD, 512MB Radeon 4850M, 1Gbit wired ethernet to same switch as Mini

OS X 10.8.5

Windows 7 64-bit, SP1



iMac, OS X Mountain Lion (10.8.1), Late 2009 i7, 16GB, 2TB HDD

    Ok, did some further experimentation.


    The same movie plays perfectly on:


    My iMac (OS X), 13" MBP (OS X), iPhone 5S, iPad 2, iPad Mini, 2 AppleTVs


    It will NOT play on the iMac (Windows 7) or the MacBook Pro (Windows 7) using iTunes 11.1.1


    The two machines CAN play the same .m4v file outside of iTunes (using VLC) perfectly.


    The problem is absoutely iTunes.
