Hi Nikon,
On the TV it only tunes at channel 3 and i don't have any other console that tunes on that same channel to try it out.
The console works great on my girlfriend's tv, a Philips LCD.
I went to the store today with the console (big hit amongst the sellers). Tried several TV's, Samsung, Sony, LG, etc, one of them with input lag of just 16ms.
On the Sony the sound comes up ok but it lags a bit on the response time. I notice it clearly with the game Fast Food. On my girlfriend Philips the movement on that game is smooth as silk. On my Sony Bravia movement smooth as silk too but no sound. Lol i'm becoming desperate.
Maybe my next step is to try a Plasma, i've heard the input lag on those is really low compared to LCD's. Or as a final resort a big fat CRT!
P.S.: Already tried with 2 RF cables.
