Before doing anything with the DTS, it seems to me it would be helpful to verify whether there are actually any differences from the Bluray audio.

If the Blurays do indeed use the same audio mixes, as I strongly suspect they do, then there would be little purpose in going to the effort synching and editing together a lossy source when full quality lossless versions are available.

Thanks for your help with this hairy_hen.

I think interest in including the cinema DTS comes from more of a completist attitude. Im with you 100% tho, it would be pointless and a waste of time if there identical and the bluray versions are the superior ones.

It is worth noting that the Dolby Digital 5.1 on the blu-ray sounds different than the TrueHD version, even when only decoding the core.

This maybe because of the compression as im no expert, but the TrueHD had a much bigger sound. I think even if you took this and compressed it to DVD spec DD5.1, with of the shelf or even free software encoders it would retain this.

A good place to listen would be when William Fichtner's 'Bank Manager' discharges his final round from the pump action shotgun in the Opening Sequence.
