composite input selection for cx88 driver / ATI Tv Wonder Pro

[Skunk Worx]

Am stuck changing my input selection to composite video for my ATI Tv 
Wonder Pro card. Also need to adjust brightness, contrast, etc.

I used to do it with the tvtime application, but it fails now with the 
VIA motherboard I'm using (S3 Unichrome based):

*** tvtime requires hardware YUY2 overlay support from your video card

Then I used the ivtvctl utility from http://www.ivtvdriver.org for 
awhile but that is very unstable now, and none of the several versions 
they have released will load modules properly when built against any FC4 
updated kernels.

I'm trying to find a way to work past this; here are my ideas:

1) Find a working video driver for the S3 Unichrome video card (with 
YUY2 support) so I can use tvtime again;

2) Wait for ivtv to stabilize;

3) Find another way to set the input to composite video; for example 
"cat" a setting someplace or add a configuration setting below /etc? 
Maybe another application doesn't need YUY2 to show video and adjust 
settings?

4) Surrender and install a real video card.

here is the dmesg :
