I was lookin at some 46" lcd and some only have ATSC tuners and some have both ATSC and NTSC. What is this?
You miss read your information. All tvs must have both tuners if they where made after march of this year and have an analog tuner. Older tv sets have only an NTSC tuner. There are no sets that have only an ATSC tuner. NTSC tuner: For Analog OTA reception ATSC tuner: For Digital OTA reception (required for OTA transmission after Feb. 17th 2009). There is also a clear-QAM tuner that is used to receive un-encrypted digital cable channels (i.e. local channels in HD). Ced
