A desktop computer with TV tuner allows you to turn your desktop into a television with the click of a mouse. Watch, record, and replay television shows on your desktop computer. Desktop TV tuners even allow you to pause live TV shows and then pick-up right where you left off, similiar to TiVo technology. A desktop with TV tuner lets you record one TV show while watching another pre-recorded program. You can also watch live TV while recording a different station as long as you're watching an analog program and recording a digital program or vice versa. You can receive free channels on desktops with TV tuners as long as you have the proper antenna. It's just like watching on a standard television that doesn't have cable hooked up. Analog and digital over-the-air channels are free. Analog cable, digital cable, and satellite channels require a monthly subscription through your service provider and the proper hardware(i.e. cables, set-top box for digital/satellite, etc). Desktop requirements generally include a minimum of 1 GB RAM and a 2.0 GHz or faster processor.
