I have a sony digital camcorder which has USB, Firewire and svideo out. So far I have tried the USB to pc transfer and have not been satisfied with the quality. i know usb is only up to 10mbs a sec. Svideo is perfect quality when transfered to pc but the setup is difficult. I still need to try firewire and I want to know if firewire will provide the best quality over svideo? Also I have a Sounblaster card with a firewire port and since it is PCI will their be a bottle neck in transfer or will I get up to 400 mbs with it firewire?

Also what is good video software, I plan to use principle studio, is it good or which is best!

thanks,
ty
