I am finding them through collector's. Folks who used to be projectionists or still are at various places. It is not an easy task and I've been quite lucky so far. A good number of them have come at a price but it won't be passed along to folks here.
@ dvdmike,
Yes, there are only 2 DTS-ES titles in the list so far. TPM & TWINE.
@ Silverwook,
I am keeping my fingers crossed as well. Those 2 seem to be quite elusive at this point but I will keep trying. One never knows.
I will be moving at the end of this month so I don't know how much time I will have to get most stuff out. I will have a far better internet connection once I move so that will help greatly. The other thing that can be difficult is finding a few folks who can and have the time to edit the reels together and synch them to video. I am still a newb at it and won't be proficient for a good while. If we can score some time here and there from folks who can it would certainly be a bonus for all of us.
