Digital grain on Paramount discs ?

[Lincoln6Echo]

Not sure where to post this, but I'll try here.

Anyway, I was wondering what the deal is with Paramount's and even on some 20th Century Fox discs, that they have an extraordinary amount of digital grain in their transfers. Titles like Star Trek, Transformers 1 & 2, and so forth..

I'm running into display problems where I'm getting vertical scan lines running through my picture during scenes with heavy grain. I have a Oppo BDP-83 and about the only way to get the reference quality picture that these discs are supposedly supposed to have is to cut the detail and edge enhancements down to 0 and boost the DNR up to nearly 7. The problem has seemed to have gotten worse lately. I'm wondering if it isn't my 2.5 year old Sharp AQUOS. I even played around with the TV's sharpness and DNR settings as I was watching Star Trek last night.

Also what should I set the de-interlacing mode to on my Oppo? Auto, Film Mode, or Vidoe mode?
