iTunes-QuickTime Problem.

Hi, I've recently bought the brand new MacBook Pro with Lion OS, when i try to view videos or movies in iTunes i get a message saying "This movie requires QuickTime, which is not supported by this version of iTunes."
It says this but my iTunes and QuickTime are both the latest versions of software.
Please someone help.
Thanks in advance.

What type of video files are you trying to play? Did they work in previous versions of iTunes/QT?

In summary of the video it says "Kind: QuickTime movie file"
and the file ends in .mpg
I didn't try to play it in previous iTunes as my Mac brand new.

Install Perian which adds support for a variety of formats (including some MPG ones) and give it another try.

Hey vansmith, just gave that ago but with no luck it is still giving the same message

Here's the issue: iTunes 10.4 runs in 64bit mode and some files require QT which only runs in 32bit mode. As such, you'll need to set iTunes to run as a 32bit application. Right click iTunes > Get Info > check the "Open in 32-bit mode" checkbox.

Ahh that's done the trick. Thanks for that
