There are over 700,000 HD DVD players in American homes. This has been disused on this forum. Since you are way off on such an important figure your mathematical formula is invalid and thus your whole statement is invalid.
Um, if there are 700,000 HD DVD players how do you reconcile the fact reported by Nielsen VideoScan that "cumulative [disc] sales stand at approximately 708,600 units" as of 3/18/2007?
