Please try not to top post.
For mplayer testing use the dvb-apps scan util to create a channels.conf
file. put it in ~/.mplayer/channels.conf, if you don't already have
one.
Then
$ mplayer dvb://WFOO-DT
or
$ mplayer dvb://WFOO-DT -vf scale=960:540
to play 1920x1080 content on a smaller monitor (like a 1280x1024).
