I have got Sony DCR_HC22E which takes Mini DV and i have now around 30 mini DV cassetes which is never transferd to PC. Once i tried using the normal USB cable provided by Sony but the video clarity was so poor it looked like webcam capture. I went PC world and they have dazzle card for video transfer but it don't mention anything about the clarity or image loss while transfering the movie. Now firewire cards, none of them mentiones about image satability all it says is speed of transfer, there are firewire cards from 7pounds till dont know the costly ones. If anyone can please throw a bit more information please, then the kids would enjoy the nappy memories.
