Other media formats will work, but the MP4 codec has shown solid reliability in our testing.

MP4(H.264) is the the Recommended File Format choice to use with KLite codecs and VideoMill.KLite will install codecs that will facilitate playing MP4s (and many other formats) on a secondary display device. Install and tweak the KLite Codec Pack as detailed below (unless you have your own professional codecs installed).If you want to fully understand this recommendation, read the sections below.

You will most likely need to apply the codec tweaks below for Video Mill to work properly. This can cause videos to freeze up when played on a secondary display (showing a blank screen or freeze on frame 1).
