You don't need a tv-card to be able to make movies like this, just hook your PS3 onto your HD-Recorder, record a few replays or one multiple times from different views, copy the video to your computer (via a dvd is an option) convert it to raw avi, start up pinnacle (or premiere, or if your realy want, movie maker) and start editing.
I don't want to react lightly on this vid, it looks great and the maker has some true video editing skills! Thumbs up, hat off!
