Lets just say you lost your dvd collection (fire, theft, whatever) and you received maybe 10$ a disc from insurance. Assume all your old titles are now available in HD (both formats - I dont want that argument again in this thread) Would you buy only HD (say $30) titles until you ran out of money, or are some films only worth an SD (say $15) copy? I think for me, I would only replace the discs I thought were worthy of spending $30 on, and probably would buy no SD copies. If the film isnt worth buying in HD, I probably wouldnt watch it again anyway. I have no idea why this question popped in my head. Your mind does strange things when you lie in bed at night.
