Hi. I am currently recording movies off of TV using a JVC HR-S9911U VCR. I usually record in S-VHS ET mode. Although it's an excellent VCR, I'm considering purchasing a set-top DVD recorder to replace it, mainly for the convenience of the media. However, one of my concerns about DVD recorders is recording movies longer than two hours. If I am recording a 2 1/2 to 3 hour movie with a DVD recorder, will the picture quality possibly be less detailed than what I'm used to with my VCR?
