v4l analogue TV question.
Could somebody (Andy Walls help me please) advice with next situation:
All my cards cx18 (Compro VideoMate H900) drop synchro - and TV
picture has problem.
This effect like broken analogue signal (I check, it was correct)
Are you have any idea what can helps (firmware, aplifier)?
This situation usually when all background too light and some part (at top) dark.
If picture not so brightness - all ok.
