Audigy has taken over where a lot of other folks have given up. I remember the days of break-out boxes for audio and video and just about every other I/O under the sun. The Audigy 2 ZS is clearly a throwback to a better era.
S-Video in, Composite video in, Firewire AND USB ports, and all kinds of software. A nice sampling rate and good video quality make this a great choice for portable/on-the-fly video and audio.
