Does the inbuilt freeview/freesat tuners that are installed into the tv output the picture in RGB? i assume they do, also would a freeview/freesat box give a better picture than an inbuilt tuner due to upscaling or just generally better. Reason i am asking is i am going to put a 32" tv in my back room and can't make up my mind whether to get one with freesat built in, run the cable from my Sky dish or get a good digital aerial fitted and not run Sky to that TV.
