Videos will no longer play in iTunes on computer

Question

I am running 32 bit Vista and iTunes 8.02 and quicktime 7.5.5. I just installed the digital version of Appoloosa and it either crashes iTunes or plays with a green screen. I tried my other digital copies I have watched before without a problem and they crash iTunes. I tried disabiling Direct 3D in Quicktime and even safe mode. The only thing I got was it playing in white. HELP!

Answer 1

Here is the log. Looks like its QT is crashing it. So, again, its either QT, or one of the Vista updates. I haven't tried to watch a movie on the computer in awhile so I have no idea what update in the past few months is causing the problem.
