New to forums and not sure this is the correct "section. I notice a slight pixelation anomaly on a wall in the background of a movie(not the whole wall just part of it)...would this tend to be a hardware(mac-mini processor capabilities), video card, conversion from dvi to vga issue or a DVD backup compression issue?...other than this movie looks great thanks for the instructions in Part 1 & 2...eagerly awaiting Part 3.

This is my first attempt at this and just wondering in what direction I should go to resolve this type of issue.
