There's an unknown frame missing there? I guess I could pinpoint it once I have it synched to the 2004 SE.

Its not unknown, its 3 frames from near the end of reel 3. 85223 and 85224 are the last two frames Alderaan exploding, and 85225 is the first frame of Luke lightsaber training on-board the Falcon.

Do you mean the last shot before wipe to credits?

(My 2004 DVD is sealed in polythene, so I can't even count that one.)

Using msycamore's proposed numbers (which I'm not endorsing yet) it came out to 183,826 in my script.

183.825 is the last frame of Mr.Shaw's ghost.

That's exactly what I meant ;)

My synch source has the same. I think the numbers may be accurate as I made my sources by aligning several different releases side by side and realigning each where there were sections missing. By then end of it the only release not missing frames was the DVD.

The only thing I am unsure of is where frames were missing from each except the DVD. Should they be there or not?

Is there any way to determine frame count from the DTS audio? Or at least a way it could help confirm them? I did appeal to someone who might have some access to the 35mm prints but I have not heard anything back as of yet as to whether it was possible to get such counts, "per reel", to make it easier to match via the DTS audio.

I'm not sure there is. There is overlap at the start/end of the audio in the reels and I tried the "sample-sample" trimming method, but the waveforms for the same parts look different on different reels, likely due to them being recorded in different takes from an analogue source to digital (at the end of one of the ANH reels the audio slows and drops in pitch, like a tape being stopped slowly). This makes it difficult to get them aligned mathematically perfect, which is why there is no exact science to synchronising these DTS reels other than putting them in the place they should be within a video source and making small adjustments until its perfect.
