Blockbuster has made it onto www.dumbwarnings.com with advice to rewind DVDs. I don't rent from Blockbuster - the local one went out of business because they were so behind in adopting DVD rentals. (The local ex-LD rental shop went DVD as soon as it was out, while the local Blockbuster was DVD-less for a VERY long time and by the time they saw the light it was too late.) I don't know if this warning is actually a common thing to see on their DVD cases at at least some local shops. Is it true that some shops do this?
