the problem with the video is that to solve the reverse signal, we reverse polarity
which disturb so the audio polarity because the gnd video (on tv) becomes the audio mass reference based on video signal.
for audio...do not work,in french forum, they do not use the audio ground to solve the problem, noise is very bad.
i'll see if i can make an video correcor amp.
that's enougn now...it's not the good way to proceed.because, when the author of firmware will do the correction of his firm, we must un_solder the video cable !!!
i 'll tell you of my news soon...
thanks jzurd0
