Tvheadend

Hi all,
I'm trying to use Raspbmc (3.10.24 #2, should be latest) on Raspberry Pi as backend with an HDHomerun Dual tuner on ATSC (OTA broadcast) in USA. TVHeadend build is 3.4-dirty, as shown on the web interface.

I see my tuners, and get multiplexes and services, but all except one have no service name. They play just fine in VLC when I click the play link in the services tab. Is there a reason it isn't picking up the service names from the broadcast? The HDHomerun utility picks up the names just fine, so I'm lead to believe that the info is there but not being recognized.

Anyone have hints for me?
Thanks
