I have a Sony KV32-FQ75 (soon to be replaced with a DX100) & a DAVS800. I understood on purchase that my DAV is a multi region. I tried last night to play a Region 1 DVD for the first time, it is playing NTSC. The DVD plays, however picture is in black & white. I am guessing I have to change my TV to NTSC however need some advice please. I cannot establish how to do this via normal menu, is this something that has to be done via service menu? - and if so how? Thanks!
