the downside is the high cost of Blu Ray disk production vs DVD.
surely that must be in the pre mastering stages
cos tbh i cant see either cd, dvd, blu ray or hd dvd costing any more or less than each other when all it is is a stampped image going plonk plonk plonk on an assembly line
dual layers taking a bit extra due to the two disc's involved
hence my distaste of early bird releases being bloody expencive
even old films on new formats are bloody dear compared to the cheap dvd and you have no guarantee that its been remastered to hi def and not just on a hd disc
and blu ray NOT playing dvd's ... poison challace for the bloke who thought that one up ... hence why its utter twaddle
