no problem, but beware that "home" cinema is quite a different beast than a "commercial" cinema. it's like comparing a hybrid consumer passenger vehicle to a mack truck

. first u might have 9.3 or 9.9 or 11.11 speaker setup or even a 22.22 speaker setup@home but a commercial cinema will still have u beat w/higher cleaner RMS power. most consumers have 7.1.
as for video, while the lines of resolution might be similar, the quality is VASTLY different. if u follow the link to the wikipedia on Digital Cinema, in addition to resolution, on the commercial front you're projecting 300"+ diagonally, while@home the best your consumer projector is likely to get to is 100" before you run out of physical real estate. not only the size footprint, but the projector needs to have VERY HIGH lumens (dunno the details) close to 35mm projection AND be at a huge size! there is no way u can just take ur $2,500 1080p consumer projector and sprawl it out on a commercial cinema. but actually they do use that, ONLY for slides/TV advertisement BEFORE the film starts. when movie trailers begin, they switch back to the REAL projector, so u can actually see the visual differences of a consumer projector and a commercial one. the consumer one doesn't have enough brightness/contract light output to match a commercial projector.
furthermore the home theater chain is limited to 8-bit video SOURCE encoding on Blu-Ray, DVD, HDTV, etc. the spex do not include anything better. i dunno if the commercial ones do encode the source@10,12,16-bit color depths, but the equipment chain can play that back i believe. not interloped, or software-jigged, but real authentic 4:4:4 lossless video playback. so video-wise that's quite a huge difference.
that's not even getting to the 4k business, lol. IMAX i believe is 4k-capable, especially those 3-D digital full-sized true IMAX versions, not the IMAX-lite (fake versions). that for sure has 4:4:4 HDR lossless video.

So, what we are seeing at home on blu with a nice set up is pretty much the same as a theater at 2k. Interesting.
Don't you think theaters should go to 4k asap so that they can say that you're getting something beyond what you're getting in your living room?
