I have a AIW 9800 Pro but i can't use the tv tuner because i have
satellite tv. Is there any software program that can decode the
digital signal? or does anyone know of any other way to do this or
know of a tv tuner card that can decode digital signals??
Where are you located? If you are in Europe you may be able to obtain
such a board. In the US the only boards available are the ones that
support NTSC or PAL composite video, S-Video, analog broadcast, or ATSC
digital, which is used for over-the-air broadcast but not for digital
satellite or cable.
If you are in the US and using DirecTV then get a DirecTivo.
