Tvheadend

I am running Ubuntu 10.10 with xbmcubuntu 2.11 with latest Tvheadend 2.13, when I go to http://localhost:9981/extjs.html and click TV adapters I then see only General and Services tabs, in General tab I click on adapters and I see my tv card (Hauppauge WinTV PVR-350 ivtv PCI:0000:01:08.0), Multiplexers tab is missing? in the documentation (https://www.lonelycoder.com/tvheadend/documentation) it says to click on General Tab and then "Add DVB Network by location" and then the adapter should be populated with multiplexes, but "Add DVB Network by location" isn't an option either.

:-(

I installed using commands for the pvr:

Ubuntu 10.04, 10.10, 11.04 & 11.10 - PRE XBMC Eden 11.0 (testing), with a PVR, you can from the XBMC-PVR repository of Alexander Surkov install.
?
1 sudo add-apt-repository ppa:alexandr-surkov/xbmc-pvr
2 sudo apt-get update
3 sudo apt-get install xbmc tvheadend
