Please install v4l2-ctl (probably in a v4l2-utils package) and mplayer.

Kill the mythbackend, if it is running.

Then run v4l2-ctl --list-devices, to see what card corresponds to which
devices nodes.  For example:

        $ v4l2-ctl --list-devices
        Hauppauge HVR-1600 (PCI:0000:03:00.0):
                /dev/video0
                /dev/video24
                /dev/video32
                /dev/vbi0
        
        Hauppauge WinTV PVR-150 (PCI:0000:03:01.0):
                /dev/video2
                /dev/video26
                /dev/video34
                /dev/radio2
                /dev/vbi2
        
        Hauppauge HVR-1600 (PCI:0000:03:02.0):
                /dev/video1
                /dev/video25
                /dev/video33
                /dev/radio1
                /dev/vbi1

On a device from which you wish to capture S-Video, set the proper input
and analog TV standard using v4l2-ctl:

        $ v4l2-ctl -d /dev/video0 --list-inputs
        ioctl: VIDIOC_ENUMINPUT

Turn on your S-Video source, and then just capture an MPEG live with mplayer:

        $ mplayer /dev/video0 -cache 8192
        
or capture a file for later playback

        $ cat /dev/video0 > foo.mpg
        ^C
        $ mplayer foo.mpg

Looks like an untuned tuner input driving the encoder, not S-Video.  An
S-Video input that is connected but has no signal is usually a solid
grey or black screen.

greping for 'cx18' will miss any error messages reltaed to the tuner
chips and initialization.  Anyway, the HVR-1600 lloks OK from what you
provided.

Your computer's BIOS has an ACPI bug that is unrelated to the video
capture cards, AFAICT.
