Tvheadend

I do my initial scan, get several channels with 80% - 100% signal, no services are displayed in the services tab. As such the "Map DVB services to channels..." button is greyed out.

Here's the debug log from a typical detected channel:

Feb 09 23:51:28 eit: install table handlers
Feb 09 23:51:30 dvb: "213,028 kHz" on adapter "WinTV-HVR 850", status changed to Bursty FEC
Feb 09 23:51:40 dvb: "213,028 kHz" on adapter "WinTV-HVR 850", status changed to OK
Feb 09 23:51:49 dvb: "/dev/dvb/adapter0" tuning to "183,028 kHz" (Autoscan)
Feb 09 23:51:49 uk_freesat: install table handlers

Tuner: WinTV-HVR 850
Works with: MythTV (Mythtv's backend is disabled so as to not interfere with tvheadend) and Me-TV
OS: Lubuntu 12.10

I do have an epg grabber configured (Schedules Direct, as I'm in Canada)
All local stations are Digital.
When using "Add DVB networks by location...", I selected United States/us_ATSC_center_frequencies_8VSB as we're on the same frequency table as the USA is for broadcast.

Help?
