You may have the same issue that I have. A profile recording issue...

google: "site:www.mythtv.org tomas chico" or read 

Talking with a couple of friends that tried mythtv I found that this 
issue is more common then I espect, I believe that the mythtv team 
should try to make visible the solution. Those friends decided that 
mythtv was not good :-O, one of them has one of those very good card, 
and so he was a success.
