I've put the insmod settings for bttv below. More than likely your problems
are with one of these options. Playing with the pll option made a big
difference, originally I didn't have it and things were real fuzzy. Once I
added it everything got crystal clear.
My modules config file looks like this. straight from the bttv docs.
# i2c
alias char-major-89 i2c-dev
options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1
# bttv
alias char-major-81 videodev
alias char-major-81-0 bttv
options bttv card=64 tuner=2 pll=1
options tuner type=2
bttv.o
the bt848/878 (grabber chip) driver
insmod args:
card=n card type, see CARDLIST for a list.
tuner=n tuner type, see CARDLIST for a list.
radio=0/1 card supports radio
pll=0/1/2 pll settings
0: don't use PLL
1: 28 MHz crystal installed
2: 35 MHz crystal installed
triton1=0/1 for Triton1 (+others) compatibility
vsfx=0/1 yet another chipset bug compatibility bit
see README.quirks for details on these two.
bigendian=n Set the endianness of the gfx framebuffer.
Default is native endian.
fieldnr=0/1 Count fields. Some TV descrambling software
needs this, for others it only generates
50 useless IRQs/sec. default is 0 (off).
autoload=0/1 autoload helper modules (tuner, audio).
default is 1 (on).
bttv_verbose=0/1/2 verbose level (at insmod time, while
looking at the hardware). default is 1.
bttv_debug=0/1 debug messages (for capture).
default is 0 (off).
irq_debug=0/1 irq handler debug messages.
default is 0 (off).
gbuffers=2-32 number of capture buffers for mmap'ed capture.
default is 4.
gbufsize= size of capture buffers. default and
maximum value is 0x208000 (~2MB)
no_overlay=0 Enable overlay on broken hardware. There
are some chipsets (SIS for example) which
are known to have problems with the PCI DMA
push used by bttv. bttv will disable overlay
by default on this hardware to avoid crashes.
With this insmod option you can override this.
automute=0/1 Automatically mutes the sound if there is
no TV signal, on by default. You might try
to disable this if you have bad input signal
quality which leading to unwanted sound
dropouts.
chroma_agc=0/1 AGC of chroma signal, off by default.
adc_crush=0/1 Luminance ADC crush, on by default.
bttv_gpio=0/1
gpiomask=
audioall=
audiomux=
See Sound-FAQ for a detailed description.
remap, card, radio and pll accept up to four comma-separated arguments
(for multiple boards).
tuner.o
The tuner driver. You need this unless you want to use only
with a camera or external tuner ...
insmod args:
debug=1 print some debug info to the syslog
type=n type of the tuner chip. n as follows:
see CARDLIST for a complete list.
pal=[bdgil] select PAL variant (used for some tuners
only, important for the audio carrier).

Ah, okay, that makes some sense I guess. Darn,
thought I figured out the source of the problem :-)

Yup, that's definately it. I tired a couple other
channels, and the 'tuner=' value was the same as the
'channel=' value.
Hrm, if the MPlayer frequency table is screwed up (and
I know that was just a guess on your part), is that
something that I can fix in the config? I have tried
both 'us-cable' and 'canada-cable' (since I live in
Canada), but with the same result.
