I have a H23-600 Directv Satellite Box, and a WinTV-HVR-950Q connected with s-video and composite audio. I'm getting blurry pixelated videos when recording with lines on top of the video. Ive decided to take back my tv-tuner and try to get a different tuner. I want to get same quality as it appears on the t.v. anyone know what tv-tuner i should buy?
