I use tvtime and mplayer to view ATSC and NTSC content OTA.  I have
the same input for both and prefer not to split it due to loss.
Anyways, with 2.6.24 series and below the drivers seems to pick the
inputs 'properly' for my needs.  Now they don't.  I looked through the
source and it seems that things are being structured more sanely.

I have the following output when I set debug=1 for tuner_simple and
run 'mplayer dvb://',

tuner-simple 1-0061: using tuner params #1 (digital)
tuner-simple 1-0061: freq = 509.00 (8144), range = 2, config = 0xc6, cb = 0x44
tuner-simple 1-0061: Philips TUV1236D ATSC/NTSC dual in: div=8848 | buf=0x22,0x90,0xc6,0x44


I don't get any output when running either tvtime or 'mplayer tv://'.
Is there some userspace ioctl call that should be made to set the
antenna input for NTSC content?  I also tried setting the atv_input
and dtv_input values.  This didn't seem to change anything.

I started getting lost in the code.  Why does simple_std_setup() check
for V4L2_STD_ATSC and then unconditionally use atv_input?  Maybe that
simple_set_rf_input() is undone at a later time?

Thanks for any info.  Search engines are sparse with information on
tuner_simple parameter information.  Although I expect I need some
code that does ioctls to the tuner modules.

Regards,
Bill Pringlemeir.

Hi
  I believe you want use module options  for tuner_simple.  To my knowledge
this can be set only at module load, Specifically  atv_input and dtv_input
for analog and digital respectfully,

V4L support for the KWorld ATSC120 is limited.  There a numerous threads 
here which talk about the problems and some work arounds.  The 
developers have talked about adding support but consider new features at 
the cost of an overhaul of the current driver.

Right now I believe you can not use both ATSC and NTSC tuners w/o power 
cycling your computer and bringing it up with (only) the appropriate 
driver.  Also, I don't believe the IR receiver works under V4L.  This 
card replaced the Kworld 110 and Kworld 115 tuners.  If you can find 
these older Kworld ATSC tuners, I would buy them instead as I believe 
they are better supported under V4L (I also have a Kworld ATSC110 - but 
only use it for ATSC tuning as well).

Go here and read up on how people are setting this card up:

I'm using the Kworld 120 as an ATSC tuner and nothing else in a Debian 
mythtv slave back end system.

I have experimented with this a bit further.  Here are some of my
observations,

I switch the antenna feed between top and bottom inputs with no effect
on getting the NTSC signal.

Loading with a 2.6.24 (non-SMP) kernel and rebooting will allow the
NTSC signals to be found by tvtime and mplayer.  Running mplayer with
'dvb://' losses the NTSC signals.  I was booting *without* module
support previously.  My kernel is now SMP with power support (I
believe that 2.6.27 is the first kernel with SMP, but I had other
kernels that seemed to also break the NTSC without SMP).

I change my 2.6.27.7 kernel to use modules for the saa7134.  On advice
from others I used the /etc/modprobe.d and created a v4l.local file,

install tuner_simple modprobe -i tuner_simple debug=2 atv_input=2 dtv_input=2
install tuner    modprobe -i tuner debug=1
install saa7134  modprobe -i saa7134 disable_ir=1 alsa=1 video_debug=1
install tveeprom modprobe -i tveeprom debug=1

I unloaded and reloaded modules.  When I do this, both tvtime shows no
signal and 'mplayer tv://' give 'static'.  This seems to indicate that
the analog path is configured, but the tuner is not working.  After I
run 'mplayer dvb://', the 'mplayer tv://' just displays a black
image. [the applications are functioning with the 2.6.24 kernel].

Reading about this card, I would expect the tda9887 module to be
loaded.  It seems that loading this module re-activates the static in
'mplayer tv://'.  I don't see any reference to the tda9887 when I load
the saa7134 (in debug, in /sys/module, or with lsmod).  Either that or
something like "tuner-simple 1-0061: using tuner params #1 (analog)"
in the dmesg output.  However, the KWorld ATSC 110 has the
'has_tda9887' set.  Is there some problem with my config?

[... blah blah blah ...]

I did investigate some of the difference between 2.6.24 and more
recent kernels.  The code is far better; user should expect some pain.
I was just hoping I was helping with a new issue; but I guess the
kernel lags behind mecurial.

Google was not helpful at showing me this thread.  I patch and used
'rmmod tuner; modprobe tuner'.  This allow NTSC reception.

No, having an i2c driver muck with a tuner is not nice (it is what was
in the 2.6.24 kernel).

Couldn't the nxt200x driver be placing outputs in OC state via a
'hw_init' and 'hw_fini' type callback (or maybe
hw_quiescent). Switching between analog and digital demodulators would
need something like this?  When tuner-simple switches A/D, it needs to
make a call up to the main saa7134 driver to ask for the demodulators
(nxt200x) to be put in the right state (or is the saa7134 already
aware of this switch?).  At least, that is what somebody who knows
nothing about this code would expect.

Thanks,
Bill Pringlemeir.
