   After spent one week to upgrade linux version and download/compile
MythTv,  finally I got it running.
   The problem now is that it can find the channels during the setup, but
when I select live tv in Mythfrontend,  it shows a black screen with
channel/program information at the bottom, I can change channels but all of
them are black screens.
   I am able to view "live" Tvs via VLC program.  And even in Mythtv-setup
it scans and found the channels.
   I looked at mythbackend log, seems problems reported by "ChannelBase"
module which have something to do with the tuner,  seems in "live" TV,  the
tunner can't be controlled so the singals can't be
   Does mythbackend calls some "external" (shell command) program to control
the tuner??

   I'm running the Mythtv on Fedora FC8 and the mythtv is the newest version
I can get this year(2008).

   Thans a lot


Following is the log info,  I'm using tuner 1 for local broadcasting with an
