To a very large extent (perhaps exclusively) the video quality is dependant on the hardware. This is standard kit, a philips tuner and Conexant ADC. There should be no difference in video quality between this and any other similar card, regardless of the drivers. Using deinterlacing type programs could be considered a software helper, but the picture still has the noise in it.
Video quality depends on clean input. These cards in general don't have sophisticated filtering as found on consumer TVs, and on a computer monitor any noise present is more easily seen. The card may be (likely is) just displaying the noise present on your analog input. The only solution is to decrease the noise, or increase signal-to-noise ratio.
I'm no expert on doing that, a Google search will find a lot more info than I can provide, but in particular be mindful of routing cables away from magnetic interferance, use (reasonably) decent quality and construction cables, connectors, and use as few (or no) splitters as possible... It's better to have a straight line unsplit to a device like this, and have split (and amplified if necessary) lines to regular TVs). Don't allow any cable lines to remain unterminated, especially not a connector cable with it's center conductor sticking out. If your entire residence has poor signal arriving at the box outside your only recourse is to have the (cable?) techinician check it, though they may bill you if you have them come inside and check YOUR internal wiring, if you've modified it in any way.
