I just got this projector, and to my surprise there was an attachable lens filter in the box with a note explaining that it should up the contrast levels. I hadn't heard about a filter being supplied with the Cineza before - does anyone have any experience with this? It's a pinkish/purplish filter (maybe like the Hoya FL-D filter that seems so popular?) - and it does seem to darken the greys at the expense of some brightness and perhaps a little colour-shifting. Haven't given it my final verdict yet. For now I'm in favour of it. Another matter: How do you enter the service menu!? And what's the "good stuff" in there to play around with? And finally another one for you fellow Cinezans (!), do you find this projector to give the best results with PAL or with NTSC DVD's? (Using the internal scaler and deinterlacer).
