Well I've fallen into the trap of starting a thread, and then trailing off as time goes on. Guilty as charged. Now that doesn't mean I haven't been working on the room, just that I haven't been updating as often as I would of liked.
So in saying that I've collated months of photos and will be posting those up over the next few weeks.
One of the reasons for the delay to the work was 2 sets of double doors I purcahsed a while ago, and only now have got around to installing, sanding, staining, etc. Working full time with 2 little ones under 3 means time is short, so I work on the HT/projects when I can. Here is the work on the doors that kept me busying for many weekends....staining to the level of complete smoothness takes some coats, and some time.
The openings on the left and right are where the doors will go. One leads to a study the other to a formal lounge room that will be a standard lounge room once the HT goes in.

From the other side, note my dirty work clothes strewn on the floor, whoops.

One door in, the frame installed for the 2nd.


Set up in the garage for staining. You can see the HT deliveries of batts and some old batts which came out of the ceiling. Also there is a few cartons of green glue and sealant on the floor. The same amount is on the other side of the table.

Taping all of those panes on both sides x 4 is a...well, a pain.

I'll post a completed pic of the doors next.
And here's the completed home theatre! Yeh baby, rocking!

7.1 installed and looking good. Actually I was just testing the cabling and general layout. Everything seems fine.

Also next will post what happens when you don't know how to remove a ceiling correctly...whoops.
