I've prepared a patch that solves blue faces on saa7134 based card.
I've wrote it over vdr-plugin-analogtv-1.0.00 and is available on my home server: http://tux.dpeddi.com/lr319sta/vdr/analogtv-20071204.diff
Included in this patch a minimal makefile for v4l2-ctl (I've renamed it to vdr-v4l2ctl to avoid conflict)
This should be used to look what control ctrl are available for the card and what is the maximum value of each control.
Then, with readed value you could fill out plugins.analogtv.conf with:
-b 255 -s 127 -c 127 -h 0
Since saa7134 card hasn't hue control, by setting -h 0 the hue control is not displayed on plugin setup screen and the control is not initialized on channel change.
Perhaps I could write a small post-install that use v4l2-ctl to initialize automatically plugins.analogtv.conf.
My patch don't work over v4l(1.0), but I think v4l(1.0) support only few cards brockertree based.
