If you will make the room windowless, you will hit a bulls eye, a geniune theatre has to be without the windows, among the advantages are, sound quality of the room will improve, there is no question of dust and sunlinght from outside, and most importantly the theatre interior effect will improve dramitically. I think there is no need of any elevation, just keep the room open for an hour during the day and once a week, keep it open for the night. The elevation will fall in place, because when you install a split air condition, the unit will have to be outside, so that small window will do the job of elevation, but this window also should have a wooden door if the need be, so you can even open this window for an hour or so once in every 2 days.
Indeed by watching movies via blue ray player will take you a step forward, but then i feel it is not much worth it, because movies are like a thermocal glass, most of the times we will not watch a movie again, so then why spend so much on a thermocal glass? I think in one's movies portfolio, one should not have more then 3% of his collection in blue ray. There are more benefits with digital movies (ripped) compared to a blue ray.
Vinay.
Pray to home theatre god that such a situation does not arise, as insult is a insult.
