I don't get that. Why can't we get the same blank media that the big companies use to burn dvds?
They don't get 'blank' media, it's pressed in special duplicators... I think, like commercial CD's. They aren't burned like consumers do. In addition, Commercial DVD's (many) have dual layers. There's a technical limitation on burners (and/or media) at this time preventing them from offering that option. (There's also the dual side dual layer option, not sure if any commercial dvd's are available with that though, never seen one, and I think marketing wise they are happier saying 'dual discs' than 'one double sided dual layer disc').
There's also the option of dual sided media but for most discs that's not an issue, if you have to flip sides you could just burn another dvd since you have to change it in the player anyway. Probably better with 2 discs anyway, there are cdchangers but none that flip sides automatically to my knowledge.
Anyway, it seems like copy protection but I think it's more a cost and availability of technology limitation.
I haven't done any research lately so some of my info above may be wrong or outdated.
