Indiana Jones is owned by Paramount, no wonder. :p

My memory of TOD is the strongest since that's my favourite (yeah, sue me), and I can tell you that film looks exactly the same as the DVD, at least in general terms, so as far as I am concerned the disks look the way they are supposed to, more or less. There is probably less grain than there should be because of Lowry, but only a bit (the prints I've seen, especially the first two films, have been a bit dirty because of their age...which adds its own charm, I guess).
