Hello,
I'm Ubuntu 6.06 LTS user on kernell 2.6.15-27-k7 with the last
v4l-dvb sources compiled to make
this Pinnacle 310i runing dvb-t with dvb-fe-tda10046.fw firmware.
Being from France I use the secam videostandard and everything is ok
for analogue tv.
Here is the dmesg output when probing saa7134 module with secam=l

I want to add that I've already manage to have dvb-t on my Ubuntu
with an other card.
So, from where come this trouble ; hardware, configuration ?
Thank you for any help you could give.

I think the "initial tuning failed" is not a problem. In this
configuration,
the channel decoder needs some time to settle. This can give you a
timeout
in the first attempt, the second should be better.
I guess your problem is that your initial config file is not ok:
Some drivers ignore the parameters for FEC, guard interval etc. For the
TDA10046, you need to set them to AUTO to let the chip determine these
automatically. Unfortunately, there are some bad config files floating
around.
The other issue is that in some countries, the transmitters are off the
channel frequency by +/-167kHz. This is the case in Britain, France and
Australia, probalbly others too. In the current implementation, you need
to correct this manually.

Hi Hartmut,
the « other issue » is the right one :
I just had to shift forward by 167 kHz each channel frequency in the
tuning data file to make the TDA10046 driver locking channels.
I wanted to notice that thanks to saa7134 ALSA driver, sound is ok for
dvb-t but cable connected from card to pc is needed for analogue tv.
It's not a problem indeed.
Thank you Harmtmut for sharing your big experience.
Cabrito
