I am buying one of two Samsung sets soon and I need some help in deciding which one. My options are the TX-P3075WH or the TX-P3064W. Both sets are 30" widescreen models. The only two differences between the sets according to the Samsung site are that the 3075 WH has a built in tuner and a different comb filter. The filter on this set is an "8-bit 20 MHz 3D Y/C" and the filter on the 3064W is a "3-Line Digital". I would like to know what the difference between these two filters might be and when the filters come into play (when watching DVDs, watching cable HDTV programming, watching OTA HDTV). There is a $200 difference in the price of these sets but if these filters make a significant difference it may be worth the $$$. Thanks for any and all help.
