Now that's really odd. I have started work with the help of the LD mono track from PDB, but this LD version seems to be even more cut than the R1 Theatrical DVD version!
For instance, there are missing pieces from the initial walk-up of the three bounty hunters trying to attack Tuco (first scene in film); also, in the encounter between Angel Eyes and the farmer (second scene in film) the line "You coming from Baker?" is missing.
The R1 DVD was intact in these scenes, strangely.
