From your train of thought (starting with cam quality) I suspect you had it in mind, but you forgot the biggest reason in your list: > Piracy has far more effect on DVD sales. This is for 4 reasons. The price of DVD's, the inconvenience of going out and getting the DVD, the bullshit adverts and unskipable junk before the film and the menu which takes 20 seconds to display before you can press PLAY. You forgot to mention your main point about quality! The moment the DVD is released, the DVD is available to pirates for their dvdrips. whereas you don't get a copy of the theater reel to play with just by buying a theater ticket, leading to the cam-rips you referred to. so, purely for that reason given that pirates distribute high-quality rips once they're available, you would expect this effect on DVD-sales to figure prominently in your list. (I'm sure you had it in mind but just forgot).
