Quicktime player doesn't work
I was accessing the following page to watch some trailers http://trailers.apple.com, and when I select the movie trailer to start the page the movie trailer doesn't work and there is a black page.
I'm using the latest version of Mac OS Yosemite and the last version of Opera browser - 30.
The trailers works smoothly on safari.
I would like to know if there is any compatibility problem between quicktime and Opera browser, since quicktime is a mac built-in program.
I also have the latest version of Adobe flash player... 18.
The movie trailers sill don't play.
