Yes, that's normal. There're still a lot of unknown scePsmfPlayer functions, so I've used the Media Engine to load and play the videos externally and that's why you can't take screenshots.
Orphis is trying to reverse the scePsmfPlayer module so, hopefully, we'll be able to understand better how it works and achieve a full implementation similar to the one used in sceMpeg.
