.Mov received as Outlook attachments are rotated

All .mov videos show up rotated in my MS Outlook. I am running Office 2007 on Windows 7. (On my other machine, Office 2007 on XP, the are fine.) If I save the video and then play it the rotation is still there.

I have tried different viewers, but the result is the same. Wmv's are fine.

As all the .mov's are of my new grandaughter I actually kep them and it is getting to be a pain to run them through a video converter.
Any help will be much appreciated.
