I don't know if you mean digital or analog tuner.

My first suggestion is to take MyhtTV out of the equation.  It
introduces too many unknown variables when troubleshooting.

To scan for channels use the dvb-apps.  Here's what I do for OTA ATSC
scanning on an older Fedora distro:

$ scandvb -A 1 -v -a 0  /usr/share/dvb-apps/atsc/us-ATSC-center-frequencies-8VSB

Obviously you'd need to run the command a little differently for ATSC
channels with QAM.

This can be used to build a ~/.mplayer/channels.conf file.  Then you can
use mplayer to test/watch digital stations:

$ mplayer dvb://WFOO-HD -cache 8192

(Note the Mythbackend may be holding the DVB adapter open which will
prevent the above command from working)

You can also use mplayer to watch analog channels:

$ ivtv-tune -c4
$ mplayer /dev/videoN -cache 8192


The first analog capture will have a bad audio PTS or no audio at all.
This is a known bug I need to resolve.  After boot up or an explicit
"modprobe cx18", before you let an analog capture happen, do a short
analog capture with

$ cat /dev/videoN > /dev/null

and kill it after a few seconds.  Every analog capture after that should
be fine.


Regards,
Andy
