this has been discussed a lot of times in the past. yes you need a tv tuner if you want to watch what is being shown on your stb. you can use your rf-out or s-video/rca if your video card can accept video-in. there are also STB's with video link like neotionbox, discovery, etc which will let you watch the show on your pc via USB connection.Originally Posted by jjvj
on the other hand, you may try buying a pc dvb-s card. then you can tune to the satellite channels DIRECTLY from your pc.
