Its not Khu Ta Viet Ma.
Its the present time - a vampire guy is a cop (being interrogated by the court coz they found out he's a vampire) and during the movie there are flash backs of the olden days how he was not a vampire before. He fell in love with this girl... and he finds her reincarnation for the last 2 lives. but the present life she is going out with a scientist who is being seduced by another female vampire...
ring any bells?
