softdevice und runvdr problem..

Hi,
wenn ich vdr folgendermassen starte klappts:
./vdr -Ppvrinput -P 'softdevice -ao alsa:pcm=default# -vo dfb:' -v /rec -c /video -w 60 $*

aber wenn ich vdr mittels runvdr starte sehe ich kein bild und er scheind hängen zu bleiben.

hier die runvdr:

#!/bin/sh
VDRPRG="./vdr"
VDRCMD="$VDRPRG -Ppvrinput  -P 'softdevice -ao alsa:pcm=default# -vo dfb:'  -v /rec -c /video -w 60 $*"


KILL="/usr/bin/killall -q -TERM"


while (true) do
      eval "$VDRCMD"
     # if test $? -eq 0 -o $? -eq 2; then exit; fi
     # $KILL $VDRPRG
     # sleep 10
      done

und das sehe ich in der shell beim starten von runvdr:
...

aber wenn ich vdr mit ./vdr ... starte:
