I'm going to replace my 30" HDTV in my bedrrom with either a 32 or 34" one as I want a bigger picture & get my HDTV & DVR through Time Warner my cable company who supply the tuner/receiver for my HD ready set. For some reason though that makes absolutely no sense to me, Time Warner in Los Angeles, does not supply the WB & UPN in HD no matter what the plan you have. My question is, if my HD TV had a built in tuner, with the same cable connection I have now, will I be able to get the WB & UPN in full HD & would the picture be as good as the HD channels I'm getting from the cable company?
