Repair your QuickTime.
Control Panel > Programs n Features > highlight QuickTime, click CHANGE then REPAIR.
If that doesn't improve, go to
Sound (Hardware n Sound)
Under Playback tab, highlight each device and click Properties button
Go to Advanced tab and change Sample Rate to 16bit 48000hz (DVD Quality) or 96000hz (Studio Quality), OK n OK.

That didn't work either. Any other suggestions?

Do you have wifi sync turned on? If so, turn it off temporary and try again.

This was happening to me and driving me nuts. I found someone online that had me go into Realtek HD Audio Manager and change the "Default Format" around. I set mine to "16 bit, 192000 Hz (Studio Quality) and that fixed my iTunes for playing shows. I actually had to try all the 16 bit setting until I found the one that worked for me. Hope it helps....

Same here, still having this trouble. I have windows 7 and im not sure if its the RAM (though it meets the requirements of apple) any luck? =/ or even a way to watch it in SD if needed? either way, i want to watch it without it becoming unsynced.

This is nearly the exact solution that worked for me! Thank you, Austin4221.
What I did is the following:
Within the "Default Format" section, I started with the highest quality and then went down the options one by one until the video played back properly.
I hope this help you.
Thanks again, Austin4221.
