This topic is coming up lately. Could be the price breaks, so people
are thinking about it. So am I. Here's something I lifted from
another list.
"The difference between CDR speeds and DVD speeds is for CDR
speeds each 1x = 150KB sec for DVDs each 1x = 1353KB sec.
So 4x would be for CDs (4X150 = 600KB sec) and 4x for DVDs
(4x1353 = 5,412KB sec or 5.4MBps)
So recording DVD is much faster than CDR recording since DVD
drives have a higher storage capacity of 4.7 GB single-sided as
opposed to CDR 600 - 800MB single-sided and need a much higher
bandwidth for packet writing."
