I did this, but the list is pretty long (I was programing at
the time, so I had a few more tasks running ;o)). Anything
in particular, that I should look for?

I tried your patch. While Mplayer no longer stays a zombie,
it basically just inverses the problem ;o)) Now Mplayer quits
and the process is removed. VDR also switches back to the
correct TV channel, but that's it. After that you can no longer
control VDR. No amount of hitting Ctrl-C will quit VDR. I
manually have to kill all VDR tasks ;o)). So the problem
was just inversed ;o)) (i.e Mplayer quits, but VDR doesn't)

Yes, this seems to make sense. I will try your patch later today
and give you a report if your patch works for me.

Greetz and thanks,
