Sorry - my fault. Actually i didn't, just my local version had this.

Did you try xvsetattr to change some value of the xv? Maybe some parameters 
(brightness, contrast etc.) are tuned wrong?
Screenshots for comparison would be helpful.

That makes absolutely no sense to me - Xv is Xv is Xv - i do not make anything 
different than xawtv beside the extra memcpy()+XSync() in 50Hz mode and that 
i just sleep in the loop (xawtv has a thread that is nice'd). I might try to 
select() to reduce cpu-load more but thats all that can be done.
