To watch non-MPEG content on the em8300 (i.e. DivX or RealVideo) you have to

Using lavc is highly recommended. Currently there is no way of setting the fps

thing is that when you use 29.97 the picture becomes a bit jumpy. The reason for

this is unknown to us. If you set it to somewhere between 25 and 27 the picture
