I have a TV in my office which is an old fashion CRT type. It gets it's signal indirectly from my satellite receiver through an RF modulator box. The sat receiver primarily serves a HD TV in another room about 50 feet away. I would like to replace the TV in my office with a pci tuner card because the TV picture quality is not very good. The TV set next to a computer which is an AMD Phenom II X4 955/8Gb on an Asus M4A785TG-V EVO mobo and connected to an Acer G215HV LCD monitor. There is no video card in the computer. I'm not really interested in HD tv, I just want to be able to watch some occasional news and dispense with the TV. What kind of tuner card do I need?
