vdr not working with xine

I got my new DVB-T stick working with kaffeine. Now I want to make it work with vdr. I can start vdr and enter comands. When I want start kaffeine as a frontend, it tells with
> kaffeine vdr://var/lib/vdr-xine/stream#demux:mpeg_pes
it only gives me the error messages

23:01:27: xine: Kann kein Plugin für MRL [vdr://var/lib/vdr-xine/stream%23demux:mpeg_pes] finden
23:01:27: xine: Plugin kann MRL [vdr://var/lib/vdr-xine/stream%23demux:mpeg_pes] nicht öffnen
23:01:27: xine: Inputplugin gefunden: VDR display device plugin

which means basically: No plugin found. Can’t open plugin. Plugin found. ?!?

Xine tells me that it can’t find a plugin for the mrl.

I know that the plugin is there and I am using the packman version of libxine.
