Troubleshooting iTunes for Windows Vista or Windows 7 video playback performance issues

http://support.apple.com/kb/TS1718

Repair your QuickTime.

Control Panel > Programs n Features > highlight QuickTime, click CHANGE then REPAIR.

If that doesn't improve, go to

Control panel

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.

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 "Control Panel", I chose "Sound".

Then, on the "Playback" Tab, I chose the "Default Device".

Then, on the new window, I chose the "Advanced Tab".

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.
