Don't make assertions that are not backed by fact. Moreover, the facts do not support your assertions. For instance, none changes the sound channel(s). Any difference in [video] quality is more often found in the user's perception than as a measurable value.
Don't use capitals; you're in a forum, not shouting from the rooftops. It doesn't make your point more forcibly, it just looks as if you have a, er, big mouth.
'Losers' is spelt like that. (And incidentally, people who hold different opinions to yours are not available targets for your disparaging remarks. A friendlier and less aggressive stance will get you much further).
