This week's DVD sales chart from Video Business marks the unprecedented debut of *three* full-screen DVDs--Grease (No. 3), Big Fat Liar (No. 4) and Murder By Numbers (No. 10)--in the top 10. But this is even more remarkable: Although Big Fat Liar is available only in full-screen, the widescreen versions of Grease and Murder By Numbers are not on Video Business' DVD sales chart (only the top 15 are listed online) at all. That has never happened before, as far as I can recall. DVDs available in both versions often chart close together, and almost always with the widescreen ahead. Because of this revelation, I'm wondering if VB has changed its charting methods or made a mistake. (For example, Grease-Full Screen is No. 3, yet four of VB's merchants don't even carry it; six don't carry the FS Murder by Numbers.) I need to check with VB to get the scoop. But, assuming this info is right, any comments on this full-screen showing?
