*** UPDATE ***

Currently we advise to use the free LAV CODEC pack with QuizXpress. This CODEC pack can be downloaded from: https://github.com/Nevcairiel/LAVFilters/releases 

We also package this CODEC with the QuizXpress version that is currently online so in most cases it is not needed to install anything.

If you only intend to use WMV video's it is not necessary to install any CODEC pack as this format is by default supported by Windows 

*** END UPDATE ***

To use video in QuizXpress you need the proper CODEC's to be installed on your system (and on the system where you will play your quizzes if this is not the same machine). We have good experience with the Windows 7 or Windows 8 CODEC packs avaible for free from:

http://www.windows7codecs.com/

http://www.windows8codecs.com/

To install (one of) these CODEC packs, please follow the steps below:

On the first page make sure to choose 'Detailed Installation'

Agree to the license statement if you're happy with it

Click Decline on the next page if you hate browser toolbars as much as we do

On the Choose Components page scroll down to the section Other Filters and uncheck both VSFilter entries. This will prevent some incompatibility issues with QuizXpress and these components are just for providing subtitles on DVD titles

No click Install and the package should install correctly
