I just bought the dvb318 from amazon and I have a Dec 2003 build date so I know for a fact it is capable of upconverting to 1080i via component video. When I hooked it up to the rca and try to upconvert to 1080i the tv screen flashes goes black and then for a few seconds I see what appears to be the dvb318 menu screen that has jagged lines and the picture will not come through. After a few seconds it will flicker and return to I guess its normal mode say 480i or something...and the dvb318 menu will come back but it is definitely not a good picture..its fair..but nothing close to HD. The tv actual does this with all the upconverting modes whether it be 480p/720p/1080i...any time I press the upconverting button the tv just does not want to accept it. This rca rptv has a built in hdtv tuner and is capable of 1440 X 1080 lines of resolution! What am I doing wrong? Could the tv be conflicting with the deinterlacer of the dvd player? Help! Thanks in advance.
