Here is what I have found out so far:

1) Cold Boot + 
tvtime => great video + no sound + TV channel #33 (set by me)
]$ mplayer /dev/video1 => black & white, distorted video + great sound +
TV channel #33  - not set by me.  I have not yet loaded a TV channel
list for mplayer.
then tvtime again => black & white, distorted video + no sound + TV
channel #33

2) Restart 
tvtime => great video + no sound + TV channel #25
]$ mplayer /dev/video1 => no sound + no video+TV channel freezes
tvtime => black & white, distorted video + no sound + TV channel #33
]$ mplayer /dev/video1 => no sound + no video+ TV channel still frozen

3) Logout and back in
tvtime => black & white, distorted video + no sound + TV channel #33
]$ mplayer /dev/video1 => black & white, indistinct video + great sound
+ TV channel #33

4) Restart
tvtime => great video + no sound + TV channel #33
]$ mplayer /dev/video1 => black & white, distorted video + great sound +
TV channel #33

5) Restart
]$ mplayer /dev/video1 =>"Playing /dev/video1. ... Exiting... (End of
file)"
tvtime => black & white, distorted video + no sound + TV channel #33
]$ mplayer /dev/video1 => black & white, distorted video + great sound +
TV channel #33

It is as if one tv program was picking up (environmental ?) constant(s)
created by the other program and the only way to flush the environment
is to re-boot.

suggested the mplayer command that I have been using as a basis of my
mplayer tv commands i.e. mplayer /dev/video1 -vo x11 -nobps -autosync 30
-forceidx -hardframedrop -vc ffmpeg12 -idle -menu -cache 16384
-cache-seek-min 50 -mc 0 -ni

I slowly experimented (using man mplayer) with each one of the elements
of this command.  Removing or altering one element after another made no
difference to the output.  Each trial and error gave the same results as
a simple 'mplayer /dev/video1'

By the way, for the first time I am getting the following error from
mplayer /dev/video1 :

...

Previously mplayer warned me that it 
"Cannot seek backward in linear streams!
Seek failed"
