What type of connection do I need to be able to connect an ariel to the Acer Aspire Z5700 PC Desktop to use the on borad tv tuner and where can I purchase it?

To use the on board tv tuner you just need to add the tv cable to the tuner ..and after that scan the signal with the program for the tv tuner..and fix the channels..
basically the tv tuner transforms a monitor into a tv ..but it is operated from the special program for it ..and it has all functions like a normal tv ..After tuning the channels and all you can operate it from the remote ..most tv tuners have one ..
