Hi, my question is, it is normal the TVout library that is supposed to generate composite video, outputs RF video signal on all channels?
I have no signal on AV mode on several tv's, now i have analog tv transmitter? ;)

The Arduino does not, and can not generate modulated RF.  It produces a monochrome composite video.

There may be a very small component of harmonics of the 16 MHz clock oscillator.
