I can't find primetime html5 content decryption module on Internet alanrwood 19:20 23 Mar 2018 HTML5 is not built into the operating system as I understand it. It is built into the browser. Try downloading a modern browser and hopefully it should work. Guest 1234512645 20:12 23 Mar 2018 I know.But unfortunately Mozilla doesn't update their browsers for WinXp, so I have to use old version. And I wonder if there any other option how to make it play html5? alanrwood 10:14 24 Mar 2018 Try installing another browser. Do a Google search for browsers compatible with Windows XP or consider updating from XP to a later version of Windows or matbe try Linux. This thread is now locked and can not be replied to.
