In regards to SW DC, a failry big shipment of the DC set was released with 7 seconds missing. The manufacturers recognised it, and offered for all dodgy copies to be sent back, and they would in turn receive a corrected copy.
Well of course there are those collectors who see this as a limited bunch and figure "bugger this, I'm keeping it, it'll worth something in 50 years".
Problem is the anamorphic set was made from that, and we lost the footage.
To be honest an Anamorphic set will never look as good as a set done in the same fashion as TR47s as the LDs were not anamorphic originally, and as they have to captured, and cannot be digitally "ripped" converting them to anamorphic clearly does lose a lot of clarity and sharpness ort he overall image.
But what can ya do?
