MythTV is not a good troubleshooting tool - too many moving parts, so to
speak.

Instead, use the basic dvb utilities to create a channels.conf file from
the stdout of [dvb]scan and do some basic tests:

http://www.linuxtv.org/wiki/index.php/User_Information
http://www.linuxtv.org/wiki/index.php/Testing_your_DVB_device


You can then put the channels.conf file into ~/.mplayer/channels.conf
and use mplayer to test DTV:

(kill the mythbackend and then...)

$ mplayer dvb://WJLA-HD -cache 8192
MPlayer SVN-r31628-4.4.4 (C) 2000-2010 MPlayer Team

"WJLA-HD" is a channel name in my channels.conf file. (The first field
on each line is a channel name.)


If [dvb]scan can't a decent channels.conf, either the digital tuner
drivers need work, or you have signal quality problems.  Please check
the list of items here, just in case:

Unfortunately my only late model HVR-1600 is in Europe with Hans for
worldwide analog signal tuning verification.  I don't have one in hand
at the moment.  (Maybe I'll just go buy another one this week).

Andy
