I don't understand why Serif disabled the 'Find Codec' button for MP4 or any other format. I've installed 'KLite Codec Pack' (free) which has very good codecs for most all of the popular formats (including H264 MP4). So why won't Serif allow us to use them? If we use third party codecs, Serif should be off the hook for licensing. What am I missing? Kinda pathetic. End rant.

I'm stranded in 'feature locked' mode (old harddrive died). So I've been using WMV format to import media into MoviePlusX6. I use FFMPEG (free) to convert my MP4s to WMV. It converts lots of formats. FFMPEG is basically command line or batch file, so no UI. If you get stuck on syntax, drop a question here.

BTW, MoviePlusX6 did allow me to use the Klite WMV codec (using the 'Find Codec' button ), so it does work for that format at least.
