AOA. Friends I have an analogue tv tuner and a skystar 2 DVB card installed in my PC. I can see dish tv by using tv out from Dish TV decoder to RF IN of my TV card, but the picture quality is not that good probably because digital signal from DishTV decoder is changed to analogue by my TV tuner.

How can I connect TV OUT of decoder to my coax input of SS2 DVB card so that I can watch high quality picture?. PLEASE HELP. THANKS.
