I suspect something is being reprogrammed in the computer/DVD by some one who has invaded my systems here.
for what purpose?
IIRC, ordinary DVD reader (not writer) doens't have 'powerful' enough laser to 'etch' (write), just to read.
and if its original, it could be 'pressed'. those writers can't change too.
still, drives in theory might scratch the disc, look for circular scratches.
