Hiya

I'm trying to play videos I've recorded and edit them with Movie Maker. However, some of these videos are in mp4 format, and I get an error ( 0xc00d36c4 ) when trying to play via Film and TV and Movie Maker fails to open the files.

I believe I'm missing the codec for each program. I am wondering - am I missing an update somewhere that includes the Mp4 codec? Or if not, is there any recommended applications which I might download to add these codecs?

Many thanks.
