ITunes stops working when trying to play purchased video

Question

Hey Everyone,
For some reason whenever I try to play a video or TV program that I purchased from the iTunes store it causes iTunes to shut down and it won't play the video. It does bring up the player for a few seconds then just hangs and a few seconds later it pops up a message that iTunes has stopped working. HELP PLEASE. I'm on 7 64 bit.
thanks

Okay. let's first try uninstalling and reinstalling your QuickTime. We'll also take a few other explicit precautions, just in case. Best to print out a copy of these instructions, because at one stage of proceedings you won't be able to use a web browser.
Preliminaries
Download and save a copy of the QuickTimeInstaller.exe file from the Apple Website. (Don't run the install on line and don't start the install just yet. get the installer that doesn't mention iTunes.)
http://www.apple.com/quicktime/download/
*Uninstall phase*
Head into your Uninstall a program control panel and uninstall QuickTime.
Next, we'll remove any leftover program files and folders.
In Computer, open your C drive.
Open the "Program Files (x86)" folder.
Right-click on the "QuickTime" folder (if it still exists) and select "Delete".
Go back into your C drive (or whichever drive your operating system is installed on).
Open the "Windows" folder.
Open the "SysWOW64" folder.
Right-click on the "QuickTime" file (if it still exists) and select "Delete".
Right-click on the "QuickTimeVR" file (if it still exists) and select "Delete".
Empty your recycle bin.
*Reinstall phase*
Restart the PC. After the PC restarts do not open any applications. Disconnect from your network and/or the internet. Now switch off all your security software (firewall, antivirus, antispyware).
Now start the reinstall by doubleclicking the QuickTimeInstaller.exe file you downloaded earlier.
Reenable all security software prior to reconnecting to the internet and/or your network.
Does the QuickTime reinstall seem to go through smoothly? If so, try launching iTunes again and trying to play one of the affected videos. Do you still get the same iTunes error, or are the files playing properly now?
