I Have A Cust That Purchased A Vizio Tv And Has A Hitachi Dv-pf33u Dvd/vcr Combo Unit. We Set Them Up With The Universal Mx850 Remote To Operate All Their Equipment. I Have Two Issues That I Was Wondering If Anyone Could Help With. First I Need To See If Anyone Has Discrete Codes For The Inputs On A Vizio Tv? ( Input Av2 And Comp2) Second If Anyone Has Descrete Codes For The Dvd/vcr Operational Functions For A Hitachi Dv-pf33u Combo Player? Any Help Or Direction Would Be Helpful. Thanks
