This section explains how to tell which version of the required software is installed on your PC.
Currently, Channel4.com offers full support only for videos on PC. There are a number of reasons for this. One of the most important reasons is that the native Mac format (Quicktime) does not support Digital Rights Management (DRM). DRM is a system for controlling licensing of copyrighted material. You can tell if a video has DRM content if you see a message acquiring license before it starts to play. Some of our content is licensed to Channel 4 on the understanding that it will be protected in this way, including the full episodes of Lost. You should be able to view the reviews and previews, however, using Windows Media Player for Mac or Flip4Mac. Learn more about alternative video players for Macs.
Try clicking the Play button again; that often fixes it. Note that you may also see this message when the video has finished playing. Some videos are quite short, it might have played through to the end while you weren't looking. (This sometimes happens if it takes a little while to buffer and download.)
If clicking Play again doesn't help, please contact us. It would be a great help if you could send us details of your operating system and browser. See How can I check what software I've got installed?
Note there is a very specific issue that can affect people behind corporate firewalls. Please let us know if this applies to you.
If your web servers are located outside of the UK, you will not be able to view all the content on the site. This is because certain content is licensed to Channel 4 on the understanding that it can only be viewed by UK users. There are also copyright reasons why some types of content, such as the news, can only be accessed from the UK.
Channel 4 takes its responsibilities as a multi-media broadcaster very seriously including all legal and regulatory aspects, and therefore we have taken the decision to restrict access to our content in this way.
