Check to make sure that the film is going into the reader, and comeing out of the reader, and into the projector without twisting, or pulling to one side or the other. Is there any flutter from the projector that could cause jitter in the timecode? If you have a scope, look at the timecode. If you can move the reader and DTS player to another projector, you may want to try it.
By the way, I know what the LED alignment instructions say, but the pot does not adjust the LED voltage, it adjusts the gain of the opamp. You can put a volt meter accross the feed to the LED (the red and black wires soldered to the board) and adjust the pot. The LED voltage will not change.
Something for anyone having problems getting enough gain out of the opamp: clean the LED, and the solar cell that is on the back side of the board that is in the reader (you have to remove the board to get to it), and clean the optical path inside the reader.
