Tvheadend

I have a Hauppauge WinTV Nova TD with two integrated receivers and Tvheadend 3.4~precise installed in an Ubuntu 12.04 64 bit.

My problem is that when I set up an automatic recording it show just one entry in the Upcoming recordings but it records it multiple times simultaneously, this afternoon it has recorded four time the German F1 Grand Prix and this evening it has recorded three times a program.

I'm attaching a pastebin link to the relevant syslog part for this evening recording:

What can be wrong?
