Im having trouble hooking up some things to my tv. I have an old tv and was using an rf modulator and i had regular cable (Mediacom) so it wasn't a problem because we used mainly the tv and the wii. We just plugged in wii to rf modulator and the cable was plugged into cable box. When I got direct tv...it had to be plugged into rf modulator...i was told you can get something where you hook up 4 things at once to tv...i got this automatic hd switcher at walmart...and it doesn't have any place to screw in cable for direct tv...it just has ports for the red, white and yellow plugs...Im wondering if I need something else to make this work or if there is an easier way to hook up my wii, dvd player and satelitte cable all at once....I do have a DVR box for the satelitte cable if that helps...any suggestions would be greatly appreciated...im not very good with electronics so be very specific in your directions
