Hi,
Please read what I wrote about Rockchip movie making here:

Also, if you're using AVIconverter, it might help if you actually type .avi at the end of your movie names. e.g. it tries to create a film, let's say, called 'Movie' but the rockchip won't recognise it unless it's called 'movie.avi'
good luck!
