I can confirm the same fault using same tuner on ubuntu 14.04 with mythbuntu installed.
Channels scanning works but Live TV does not tune and EPG is no longer updated. I have not been able to get any video in mythtv sinns upgrade from 12.04 to 14.04 a few days ago.

Deleting all tuners and channels and inserting again did not help.

I have tested also with Kaffeine where the tuner works well.

Title:
  No channel lock DVB-T after upgrade to 14.04.1

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  New

Bug description:
  I run a mythtvsystem using DVB-T, card Hauppauge Nova-TD Stick
  (dvb_usb_dib0700). This tuner has worked perfectly up to upgrade to
  14.04.1 yesterday. The tuner initializes fine (relevant dmesg below).
  After a reboot I get channel lock about one time. When I change
  channel I get the message "You should have received channel lock by
  now". Signal strength is 42%, S/N is 2,4 db and is also says (TL_s)
  Partial Lock.

  Checking the mythbackend.log I find the following:
   mythserver mythbackend: mythbackend[2325]: E DVBRead mpeg/mpegstreamdata.cpp:428 (CreatePATSingleProgram) MPEGStream[6](0x7f39d401f528): Desired program #5820 not found in PAT.#012#011#011#011Cannot create single program PAT.

  dmesg output
