Whilst I've got no experience with Kino I suspect it uses ffmpeg or mencoder to do the actual video rendering. Both of these are able to utilise multiple cores and as such you'll notice a bigger difference using a slower quad core than a faster single or dual core processor. The motherboard in that bundle also has radeon 3000 integrated graphics, which, according to a previous reply, is supported by the proprietary drivers so performance should be decent. Adam.
