1. Model is Pinnacle PCTV 50i2. Earlier connected through RF now through Composite over S-video.3. Almost, some content is deinterlaced quite nicely while there are clear lines in some content.Composite -The composite video connector (yellow) from STB will go into the card's S-video input via the provided converter.The composite audio (red and white cables) from STB will need a RCA stereo female to 3.5mm stereo male converted jack and that will go into your sound card's line-in port.RF -1. The RF output cable from STB will connect to RF in on the card. No other cables required.Software -1. I found the Pinnacle software unstable and it wasn't giving audio for RF sometimes so I use K!TV (Kastor TV) for simplicity.2. If you want lots of options to play around with you can use DScaler for composite connections. It was unable to tune in to the RF channel.Best of luck.
