It depends, if he is connected to an analog cable, he would use the analog part.Hi and welcome tvbum (nice handle )
Were you trying to use the analog input/tuner? If so, you probably just need to install software encoders.
Having said that, based on the time that you've posted and the type of tuner the 800i is, I'm guessing that you're based in the US or Canada. If I'm right, I would have thought that you would be needing the digital ATSC/QAM side of the card rather than the analog side.
