Ive been dealing with for about two weeks now. First off My cable is already amped to an 8 way splitter with all new coax. With an older TV 1 svideo,1 composite,1 coax, Ive run from wall to another 2GHZ splitter,splitter to Tivo and TV, Tivo out on Svideo to Harmon Kardon receiver and from there Svideo to TV. My second machine wall to 2GHZ splitter, splitter to Tivo and Tv , Tivo out on RCA(red,yellow,white) both machines show about the same quality. Ive also done all the necessary suggestions removing the splitters ect.
