No. 
The problem is that in the new DVB API video and audio are separate
devices. This makes the interface cleaner and one can also better use 
both devices seperately, but it also makes the direct piping
impossible. 

The API also demands that you explicitely switch those
devices to a memory input. I guess this could also be
automatically switched if somebody writes to the device.
We also allow writing multiplexed PS streams with video and audio 
to only the video device. This is not in the initial API specs. We
added ioctls to ask the driver if it is capable of handling this.
But you still need to open the video and the audio device, also if you
only write a PS to video.
