Video only.
It would be lovely if it did audio too, and you could feed it a 
scatter-gather list of blocks from the SD to play - but no.

So we've got to decode the audio in the CPU, and feed the extracted 
video stream from the file read by the CPU to the video chip. 
(neglecting the fact that tehre are no drivers)
