I like VCRs in that you can record in a tape over and over again. I know the A/V quality isn't as good as DVD, but those aren't critical qualities when I'm just recording a show to watch later. Can a DVD Recorder do this or do you have to use a new disc each time you make a recording? Can you use a DVD Recorder the same way as a VCR as far as setting a timer to record something in the future? Where does the DVR fit into the realm of home A/V recording devices? Does a DVR require a connection to some other entity like Tivo or DirecTv or can it be used a a simple stand-alone device for recording ? Thanks for any input.
