This is assuming the quality of the analog data is perfect.  At some point,
the quality of your capture will either (a) contain more precision than is
necessary to 100% faithfully represent the original image (due to signal
noise, quality of the videotape at the transmitting end, etc), and/or (b)
exceed the ability of the TV to represent the full quality of the output
captured image.  If I'm not mistaken, TV's also display pixels, although
they're not perfectly round like a CRT's.  So there's really no point in
capturing more pixels across than your TV can show.

Again, what's the good in having a full-DVD resolution representation of a
grainy image?

Just my $.02
