well, to my understanding, hdtv's are hdtv's cause they either need a service provider who has a box like satellite or cable hd boxes to watch hd tv. or you would need a tuner box that can be hooked up rabbit ears for hd viewing cause they have a built in tuner. my doesn't have a built in tuner. that's why i needed to buy one. my tv doesn't have an coaxial plug. most older hdtv's didn't always come with them. now they almost all the time come with them. i just don't know the difference really between the tuners. although i have a samsung tuner DTB-H260F but this doesn't allow me to watch any cable. i scan my tuner for cable and air and doesn't give me any channels. not sure why? anybody knows why?
