- I too have an XBR and a JVC S-video deck and have noticed the same thing.
- What I concluded upon careful observation of the picture was that the video
- appeared to have more bandwidth from the S-VHS VCR. This makes a certain
- amount of sense if you assume the VCR tuner was designed for maximum bandwith
- to take the greatest advantage of the format, the noise figure is likely to be
- higer as well.
