I think you need to setup with the mythsetup.

I don't remember excalty how but it's linked to the ivtvctl system.

I'd suggest that you find your correct colour output using the dd
command, and then work within the setup program to select the correct
output.

To work it out using ivtvctl:

Check what outputs you have and which one is in use.
[mythtv at olympus ~]$ ivtvctl -N
ioctl: VIDIOC_ENUMOUTPUT
        Output  : 0
        Name    : S-Video + Composite
        Type    : 0x00000002
        Audioset: 0x00000001
        Standard: 0x00000000007F3FFF ( PAL NTSC SECAM )

        Output  : 1
        Name    : Composite
        Type    : 0x00000002
        Audioset: 0x00000001
        Standard: 0x00000000007F3FFF ( PAL NTSC SECAM )

        Output  : 2
        Name    : S-Video
        Type    : 0x00000002
        Audioset: 0x00000001
        Standard: 0x00000000007F3FFF ( PAL NTSC SECAM )

        Output  : 3
        Name    : RGB
        Type    : 0x00000002
        Audioset: 0x00000001
        Standard: 0x00000000007F3FFF ( PAL NTSC SECAM )

        Output  : 4
        Name    : YUV C
        Type    : 0x00000002
        Audioset: 0x00000001
        Standard: 0x00000000007F3FFF ( PAL NTSC SECAM )

        Output  : 5
        Name    : YUV V
        Type    : 0x00000002
        Audioset: 0x00000001
        Standard: 0x00000000007F3FFF ( PAL NTSC SECAM )
[mythtv at olympus ~]$

[mythtv at olympus ~]$ ivtvctl -L
ioctl VIDIOC_G_OUTPUT ok
Output = 0

Then try the various outputs (I'd only really suggest using the first
3) (the -l is lowercase L)
ivtvctl -l 0
ivtvctl -l 1
ivtvctl -l 2

Again, don't test the output using myth as (from memory) it sets the
output dependant upon it's setup, so instead use the dd command.

Hope this helps,
Ant.
