Having experienced problems with black & white pictures on my non NTSC compliant TV, I have hooked up my PS2 to the DAV to enable me to play my R1 discs in colour. The picture is fine, however, the unit does not decode to Dolby Digital or DTS. Is this because it is an all in one unit and will only decode if a DVD is played from the DAV? Or is it not confgured properly. Any suggestions would be appreciated.
