Our website uses a host of advanced features that have only recently become technically possible.
Variable speed playback is such a feature.
Browser manufacturers are racing to catch up with many of the features implemented in the new HTML5 specification and some are doing better than others. All of the "Big 4" browsers (used by 98.5% of users) has implemented variable speed I their current desktop browsers by July 2014.
- Apple iPad (but make sure the operating system is up to date).
- Google Chrome (but not on the Android OS (see note below).
- Internet Explorer (tested with version 11 but understood to work with versions 9 and better, see note below if you have a very old operating system version).
If you are one of the 1.5% of users using a little-used browser (such as Opera and Silk) you should change to a mainstream browser when using our site if you experience problems.
If you are using a very old operating system (such as Windows XP) it is also usually a good idea to avoid Internet Explorer as Microsoft tend to only make their latest version browsers available to users of their later version operating systems (while you can always install the latest version of Chrome, Firefox or Safari)
Android had still not supported variable speed playback in their latest release at July 2014 (version 4.4.4). We've left the buttons functional on the Android as it is expected that they will shortly implement this feature. Please let us know if you have an Android/Chrome device that supports vari-speed so that we can update this advice (new Android versions are released very regularly).
