It doesn't really matter to MPlayer _where_ the data is, at this point of
the code everything is considered to be part of a frame, but there's currently
a problem when there's more than one data packet in what MPlayer considers
one frame.
Since I want to keep the code in a way that can easily be used for other
kinds of userdata adding this is going to be slightly more annoying than
just appending.
