You guys are missing something here. Its USB, hello, the data rate sucks! You're much better off with a firewire system, and they're available, but probably a bit more. You're better off hooking up your DVCamera to the firewire and using that.
This is totally aimed at the low end market. Mpeg1 and Mpeg2 compression isn't all that good, and then you have to worry about sound too.
