hiyou, If your objective is to " I would like to watch TV on my laptop." and NOT to want to necessarily use your coax cable from your external source then you can do so provided you have a high speed connection available to your laptop and it is a sufficiently recent computer with adequate RAM. You will be limited as to what you can watch by virtue of the limitations of the particular types of TV you desire to watch and whether you MUST be watching it as it is produced. If on the other hand you don't mind watching shows than can be hours to a day old then many commercial channels and PBS (U.S.) make their shows available on line. Also many channels do live web based streaming of news programming. But if you want to watch let us say a current sports event as it is happening that is unlikely to be available at initial time of broadcast. If you do want to do what i have mentioned and meet the earlier stated requirements then you don't need anything other than a proprietary software for the particular channel you want to watch. These are always made available free by the station on their website. An alternative for what it's worth depending on your desires.truenorth
