So... basically one could modify the box that surrounds your average desktop computer, ground it, add a surge protector, and have sucessfully emp sheilded their computer?

Hahaha, no. Your basic computer case has a hard enough time shielding the computer from basic EMI from household appliances, much less the terawatt EMP weapon a sufficiently technical terrorist could build. You need a much better Faraday cage than that to shield against an EMP pulse.

Problem is, you're making a copy of a copy of a copy, and so on. You get markedly deteriorating picture quality each time. The fact that you'd be making a recording of an old, deteriorating copy won't help either.

With a digital medium such as DVDs you would only get any deterioration if the storage medium itself deteriorates. With an analogue signal any variences in the signal are apparent but with a digital signal the signal would probably have to change by a third before any chage can be seen (and that's only 1 bit out of millions).

And to whomever said that DVDs were write only most DVD recorders support DVD-RW now.

Basically I see DVD-RW/hard-disc recorders taking over in 5-10 years.
