this is almost always true. if film hasn't been stored properly, it will deteriorate. I saw a film in 35mm on thursday, and the whole thing was red and white. it was barely watchable. the dvd looked better. this is the only time i have seen a film worse than dvd though.
"dvd's will always be better quality than youtube, but this one time I tried to watch a dvd that was all scratched cuz it wasnt stored properly and it was awful. thats the only time I have seen a dvd worse than a youtube video."
