vdr should pick up the second tuner automagically so there's no
need to configure it explicitly.

 Whoops!  I suppose you need to collect a backtrace of that panic...

 You may need to allow you subnet in:

	/usr/local/etc/vdr/plugins/xineliboutput/allowed_hosts.conf

 Make sure streamdev is enabled in vdr_flags, then just point some
player like vlc at one of the streamdev channels, like:

	vlc http://127.1:3000/1

 (the last 1 there is the channel number.)

 You can also point a browser at:

	http://127.1:3000/

to get a channel list.

 If you want to test the second tuner make sure the channel is on another
mux than the one you're watching in vdr-sxfe or both will be received
by only one tuner...

 Oh and there can only be one channel and osd shown by vdr-sxfe, even
if you connect more than one vdr-sxfe instances over the network, that's
why I suggested streamdev for testing the second tuner.

 Yep.

 It shuold put an entry in the vdr osd main menu, just select that.
BER and UNC (if available) readings for the currently playing channel
will be shown in the top display.

 If you use the default /usr/local/etc/vdr/remote.conf installed
by the vdr-plugin-xineliboutput port (you can look at that file!)
then the menu is on the tab and insert keys in the vdr-sxfe (or
softhddevice) osd.

 You can either check the epg via the osd (on screen display, Menu
-> Schedule, or Menu -> Program guide if you enabled the extrecmenu
plugin) in vdr-sxfe and hit Red (F4) to record the selected show,
or you can use the live web plugin if you enabled that, by pointing
a browser at:

	http://127.1:8008/

 (Default login/pw is admin/live as mentioned on the wiki.)
