   awalls_: what input does v4l2-ctl show the unit being set to?
   <br> I'm guessing Composite (aka CVBS)
   <br> v4l2-ctl --help will show all the options.
   <br> you want the command line options regarding listing the inputs, the current input, and setting the current input.  Also options for setting NTSC and/or PAL
   llldino: awalls_, http://paste.debian.net/714661/
   <br> awalls_, S-Video is set, NTSC,
   awalls_: and your svideo signal is from an ntsc source, correct?
   llldino: awalls_, It sure is
   awalls_: ok, well there go the simple solutions.
   llldino: awalls_, Is s-video properly built into cx231xx? I read a long long time ago that S-video was never supported via cx231xx, but that was over 2 years ago
   awalls_: I have no idea.  I know the chip is certainly capable of demodulation svideo
   <br> *demodulating
   <br> the input mux of the internal cx25843 is probably just being set up wrong by the driver
   llldino: Oh
   <br> I have these 2 lines in my dmesg:
   <br> http://paste.debian.net/714662/
   awalls_: the cx25840 driver handles most of the setup under direction of the main cx231xx driver.
   llldino: I didn';t know that, I thought it was a rouge mod or something
   awalls_: that's the broadcast audio auto detection firmware not being loaded into the internal cx25843, which probably makes the cx25840 driver unhappy
   <br> I'm not sure.  it's been a long time since I looked at any of this stuff.
   llldino: Yeah, audio fails if I turn the source on and off, where do I dump the .fw
   awalls_: usually /lib/firmware
   <br> but the firmware only matters for tuner SIF audio.  not baseband audio
   llldino: Still, if dmesg is complaining
   awalls_: yeah.
   llldino: SO that would have nothing to do with s-video right?
   awalls_: well it shouldn't, unless it prevents the cx25840 driver from responding to calls from the cx231xx driver.
   llldino: i'll give it a reset, see if it loads
   awalls_: http://lxr.free-electrons.com/source/drivers/media/usb/cx231xx/cx231xx-cards.c#L643
   <br> the card definition in the driver for your card.
   <br> at first glance it looks like someone knew what they were doing when they set up that definition
   llldino: Okay, so that got rid of the one error, still left with:
   <br> [    2.082246] cx25840 0-0044:  Firmware download size changed to 16 bytes max length
   awalls_: that's just a warning you can ignore
   llldino: Ok
   awalls_: http://lxr.free-electrons.com/source/drivers/media/usb/cx231xx/cx231xx-cards.c#L643
   <br> http://lxr.free-electrons.com/source/drivers/media/usb/cx231xx/cx231xx-cards.c#L643
   llldino: I don't know C :(
   awalls_: that's just a table in the driver describing how to set up your specific hardware
   <br> for Composite and SVideo
   llldino: Ah
   awalls_: it looks like the author knew what they were doing at first glance.
   <br> but there might be an error in it, if you're having problems.
   <br> and no one else can confirm working svideo
   <br> gtg.  good luck.
   llldino: Thanks for your help!
   <br> Should note here as well, the audio problems I have may be related. Audio works fine, but when I turn the input off and then back on, it seems like the audio part of the driver fails and won't play it back anymore
   <br> No errors in dmesg or anything, still shows up as an input but no sound until I restart
