I'm using the ASIO i was given with the DVS , no idea neither.I will change my OS today to windows XP SP3.May be my windows , not quite sure.I'll get back to ya if it will be still the same.
As i though , the problem was my OS which was windows 7 , i switched back to XP SP3 and its flying well.Thanks for support and I hope I wont have to come back to this section again
