Here we go :
TV_VIDEO_GROUPS = [
# Use this group for watching tv
VideoGroup(vdev='/dev/video0',
adev=None,
input_type='tuner',
tuner_norm=CONF.tv,
tuner_type='',
tuner_chanlist=CONF.chanlist,
desc='Chaines Cable SECAM',
group_type='ivtv',
),
VideoGroup(vdev='/dev/video0',
adev=None,
input_type='tuner',
tuner_norm='pal',
tuner_type='',
tuner_chanlist=CONF.chanlist,
desc='Chaines Cable PAL',
group_type='ivtv',
),
VideoGroup(vdev='/dev/video0',
adev=None,
input_num='2',
input_type='composite',
tuner_norm='pal',
desc='Entree Freebox',
group_type='ivtv',
),
]

I did some of these tests, but instead of working trough a temporary mpg
file, I did my tests using xine :
xine --stdctl pvr:///home2/media/tmp/xine-buf-
Do you think that this will create a diff ?
I did a lot of tests, tuning slightly the freq, and so on, without luck,
until now.
googleing gave me a new command :
v4l2-ctl --log-status
Using this command on a TV secam show give me :
cx25840 1-0044: Video signal: present
cx25840 1-0044: Detected format: SECAM
cx25840 1-0044: Specified standard: SECAM
Using this command on my PAL composite entry give me :
cx25840 1-0044: Video signal: present
cx25840 1-0044: Detected format: PAL-BDGHI
cx25840 1-0044: Specified standard: PAL-BDGHI
that for the cases working.
Using this command on my PAL Antenna input give me that :
cx25840 1-0044: Video signal: present
cx25840 1-0044: Detected format: NTSC-M
cx25840 1-0044: Specified standard: PAL-BDGHI
(In fact, the detected standard is not really stable, it is mostly
NTSC-M, but can be PAL or SECAM).
I suspect that the trouble is in this area (is the PAL signal of my
cable operator not totally clean ? I don't know, but our TV don't have
trouble with that signal).
Unfortunately, I don't find a stable solution, still trying.

I think that I need to find an explanation about my non working PAL
Antenna channel, but still, now I can select a PAL or a SECAM input in
the TV Menu.
Still, I cannot change from PAL to SECAM or from SECAM to PAL jumpig
from channel to channel with the 'C' and 'V' keys.
