Anyway, the picture quality seems better that expected [...]

Video signal is a bitch.
You cannot just fool around with it like with sound: Besides the much higher bandwidth (~5MHz) which makes designing video circuits much more demanding, the main problem is that video signal contains not only the actual picture, but also synchronization signals. You touch the picture and the sync goes away, the [...]
