In case anyone's seeing this using SVP3 and had no idea that 4 had released, 4 is well worth paying for, it is far less hardware intensive (SVP3 would choke getting high bitrate 1080p videos to 60fps, SVP4 handles the same files like a dream - anecdotal but better than nothing), the interface of the main application has been... improved (kinda subjective, but it's definitely more idiot proof) and it even supports VLC now if you swing that way.
