Ah, finally a part of the discussion I understand. All seriousness aside, I
do appreciate the technical background, even if it's FAR over my head. But
the end comment is something I can deal with — I made tests that have
demonstrated that, to my eye, I can detect no appreciable difference on
material recorded at any higher resolution than 640 by 480.
Now, that may mean my board doesn't support a higher resolution, but I
doubt it (it will display just about any resolution correctly) — but I'm not
really worried. Perhaps it's just the limitation of SVHS that I'm seeing.
My tests look so good that, if there's a better way of doing it, I'm not losing
any sleep over it. However, I do appreciate all the feedback
everyone has given.
