So I bought this little photo camera that also makes nice HD video. However its output has the MP4 format. Now I managed to find and download a Codec for Windows Media Player (Vista) and that works fine. However no luck to adapt Windows movie maker to MP4 files. And of course it would be nice to be able to edit and stich the different movie fragments somehow. So what to do? Are there codec's for the WMM or get alternate software for that. Any tips and recommendations?
