I use a Dazzle DVC100 and put my xbox in SD to connect to my computer with no splitters. Just use the cords from the xbox and the USB from the device. I use Pinnacle 12 for my videos. SD is not great quality but it certainly isnt awful. The video ends up coming out something like this: http://www.youtube.com/watch?v=SxO8ojSEEsI&feature=g-upl.
It's really not bad besides the on screen text and some visuals.
Anyway, my main question is how do i up the quality of my videos. Surely there is a way. Thanks in advance!
