I have a Nova-T (grundig FE) and may have the same problem. I'm not 
using mplayer though. Sometimes when vdr starts there's no picture, if I 
kill vdr and let daemontools restart it then there's always a picture 
the second time. Similarly if vdr starts for a timer recording, after a 
few seconds it will do an emergency exit because it is receiving no 
data, then it will be fine. In a previous setup I used to run dvbtune 
just before starting vdr and things would be fine.
