請問這樣在2000下正常嗎?
 

我的TV Wonder在Windows2000 Professional SP2下的裝置管理員裡面有:

ATI TV Wonder BtCap,WDM Audio Capture
ATI TV Wonder BtCap,WDM Video Capture
ATI TV Wonder TVTuner,Philips WDM TvTuner
ATI TV Wonder WDM Audio Crossbar
ATI TV Wonder WDM Video Crossbar
ATI WDM Teletext Decoder
ATI WDM Teletext Decoder(好奇怪,跟上面一樣,但是移掉又會重抓)

居然有那麼多裝置,而且使我的開機速度明顯變慢,請問這些都是必要的裝置嗎???
