It seems that I am the only unlucky with this board!

I have downloaded and installed latest CVS Mercurial but for me
card=111
(or card 112) does not work. I get some decent results only with
card=109,
tuner=67 and these changes in the file saa7134-dvb.c (and
 saa7134-cards.c):

static struct tda1004x_config philips_tiger_s_config = {
[snip]
.gpio_config = TDA10046_GP00_I, // instead of
TDA10046_GP01_I
[snip]
.tuner_config = 0, // instead of 2
[snip]
};

This is a snapshot from Xine:

That looks fine, apart from an artefact caused by a reception problem and a lack of deinterlacing.

While tuning channels Kaffeine sends a lot of messages:
"Invalid section
length or timeout: pid=xyz"

Are you also getting a lot of visible reception error artefacts? I had bad reception on one of my Nova-Ts a while ago - the problem was that a co-ax plug was making a bad contact with the co-ax core wire. One replacement plug later, problem gone.

When I watch some DVB channel Xine says: "the amount of
dropped frame is
too high". It cannot be a performance problem; my PC has a
CPU AMD64 4200
X2 2200MHz+2200MHz, video card nVidia GeForce 7600 GS (driver
nVidia) and
kernel 2.6.20 configured as SMP.

It could well be a performance problem, despite your belief to the contrary.

I find that Xv works well, normally taking about 30% of CPU time (2GHz
Sempron, running at 1GHz due to cpufreq; Radeon 9200, untainted), xshm
 works
reasonably well but OpenGL is slow, presumably due to colourspace
 conversion
requirements. (XvMC and XxMC don't work here.)


As I have specified in a previous message, under Windows XP (software CyberLink Power Cinema) the signal is perfectly stable.

It seems that with the Linux driver the tuner loses sensitivity.
