Hello,
Today I purchase a tv tuner card. It also can capture the video from tv programmes. But I get noise in video quality, Channels are not clear as they shown in TV. Can anybody inform me why this happens?

If I use any other software, can I see a clear picture? If yes, please inform me the software which will show a nice quality picture?

Also inform me how can I capture tv programmes? Inform about some softwares that captures video from the tv tuner in a good quality.

Please inform me as soon as possible.
