I am looking in to getting a Dvd Recorder Deck and have a few questions. 1-What make and model right now for the consumer is the best out there? 2-Is it possible for me to add chapters to my dvds either during or after the recording process is over? 3-What features have yet to be offered on Dvd Recorders aimed at the consumer market? I'm assuming that you cannot yet add a running commentary over some home videos.Or are not able to copy a movie dvd to a blank Dvd-R in 5.1. Digital Sound. Any help would be grateful.Thanks.
