Quicktime 10.4 on mac OSX 10.10.2 won't open quicktime 7.6.6 in a website
I have been going to some websites recently trying to see some videos. Instead of a thumbnail there is a puzzle piece and it says need to download Quicktime 7.6.6 or higher. I can't view the video. I am on a Mac desktop using OSX 10.10.2. The website has at the bottom "Made on a Mac". Can Quicktime for MAC not recognize Quicktime for Windows? How can I view these videos? It's very annoying that I can't open a Quicktime video when I have a MAC and Quicktime on my computer.
iMac, OS X Yosemite (10.10.2)
