a quick start is (iirc), to start the recording only _after_ you started 
  rendering.
that is: [pix_record] needs to have received at least one frame of the 
correct size before it starts recording (else it will immediately stop 
because it thinks the frame-size has changed).

this could be considered a fixeable issue.
