Well regarding my bum card...i just got an RMA authorization, so within two weeks (hopefully) I should get a repaired or new card.
I don't know whether its hardware or software related, but leadtek's support seemed to just authorize an RMA rather than try to tackle the problem...so thats the route im going
Although, now I am having feelings that it is hardware related...when I tried to open DScaler, DScaler would open fine, but the Winfast PVR software would somehow intervene and load too and give the "Capture device lost" error msg. Of course, If I open DScaler again after this it works fine (although the IR capability seems to go off for no apparent reason). Im hoping that a new card will solve the problem.
