Yes, there are cards for both DVB-S and DVB-S2, but none of them have blind search.
There is a section here for PC DVB Cards: Free to Air PC DVB Discussion
(Under display options at the bottom of the page you should select: "From The Beginning" to see all the results)
The advantage to having a PC DVB card is that you if you computer if fast enough you can watch HD feeds and 4:2:2 feeds that most SD receivers can not.
