Also, I noticed in the screens the appearance of grain, which you can see with a number of BD discs, my question is did you add in the grain or was it already there or did it just make it more apparent with the encoding?

Hi. If I may... grain is a natural by product of film. Its usually digitally removed, at the expense of fine detail, from DVDs because its intricate textures present compression problems.

Its often left as is in high definition video because there is both the increased resolution and compression effeciency to deal with it.

You can read more on the subject, and hopefully discover why some 'grain is good' here.
