Avermedia M779 Problem

[w1de]

Hi guys!
Recently i bought this tv tuner card to digitize my old tapes but unfortunetly it has some problems.
At first the drivers always give me a BSoD with the error DRIVER_VIOLATION and i dont know how to fix it except deleting the drivers.
And the main one is that in constantly trying to put a blue screen over the capture because of lags and noises, which really annoys me cuz the main reason why i bought it so i could see the lags and noises from vhs tapes. I know you will say its because the chip is weak BUT if ill try to watch the video in Virtual Dub 2 in overlay mode it shows completely normal picture without any blue screens and signal losses.
Can anybody help me with this?
I will be really happy if someone does=)
P.S. There are actually more problem such as frame dropping. I really dont know what to do now =(((
