Well, I just opened up ” mythtfrontend ” from client machine.
Choose “Watch TV”.. until something came up from the TV card input..
let it there..
then .. just SSH into backend machine..
( the run running mythbackend and had TV card installed)
as root run the following :
for ((NO=100;NO<=800; NO++)) ; do echo Testing ... $NO; ivtv-tune -f $NO; sleep 1; echo Testing $NO.5 ...; ivtv-tune -f $NO.5 ; done |
it shall spit something like ..
“/dev/video0: 102.000 MHz
Testing 102.5 …
/dev/video0: 102.500 MHz
Testing … 103
/dev/video0: 103.000 MHz
Testing 103.5 …
/dev/video0: 103.500 MHz
Testing … 170.
/dev/video0: 107.000 MHz
..
/dev/video0 175.50 Mhz (Signal detected)”
Basically it just keep increasing the frequency by 0.5Mhz till the end.
whenever catch a signal from station.
just mark that range..
and do further testing within that range to get proper frequency for each TV station.
Then might need to change the “frequency.c ” and re-compile the ivtv-tune and place it again at “/usr/bin/ivtv-tune”
or “/usr/local/bin/ivtv-tune”
this is what I can deduct from above experiment . at my Damansara Damai’s Home.

Hmm.. now can I can watch TV1, TV2 and TV8 clearly..
but a bit struggle to watch TV3. (bad reception quality)
very bad .. for NTV7 and TV9..
p/s : .. I think am going to get proper “Free-Air” antenna to enhance those TV signal.. a Set-Top Box perhaps..
(as someone had left the installed Astro Dish at my new home.. )
