Hi Def DVD sales actually low
 

From IMDb:

'Some Hi-Def DVD Discs Selling in the Hundreds

While much has been made of the strong high-definition DVD sales of such films as Casino Royale, The Departed, Batman Begins and Superman Returns, sales charts show a steep drop-off below the top level, with some films selling fewer than 200 copies since they were released, according to the website HighDefDigest.com. Citing figures from VideoScan, the website noted that during the week ending March 18, when Casino Royale topped the sales charts with 28,233 units sold, the "top-ten" list included one title that sold just over 3,000 units, while all the rest sold fewer than 2,000, including three that sold fewer than 1,000. The website concluded that the sales figures are "a sobering reminder" that the HD DVD and Blu-ray formats "have a long way to go in their shared quest to supplant standard-def DVD."'

Dang, I think I did one project that sold almost that many DVDs (over 100 anyway) and it sucked... and wasn't Hi Def, only mostly Def... or something like that...

Sure points to the marketing problem that "HD" faces - high prices, two competing formats with no clear winner, and no real great compelling reason to "upgrade" from standard DVDs for the "average" end user...

Hope the industry wakes up before long, low sales aren't the result of piracy... they are the result of institutionalized sillyness and arrogant championing of one technology over another while they blame bad sales on the end user... and wonder why the stuff ain't selling...
