Just watched Two Towers on DVD on my PC, and the CGI scenes are really obvious. I can't remember this being the case at the cinema when I saw it - but that was the best part of a year ago, so maybe I just can't really remember. I thought exactly the same about other scenes in a few other films that I've watched both on my PC and on my 32" TV. I can't really think of any obvious reason why this should be the case. Does the 20ft wide screen (or however big it is) in the cinema help hide these facts, or is it something else?
