what had happened is imagine this.
each channel is a seperate line able to be edited in the multi track editor.
when I've been dragging bits and bobs around to sync up, over time whats happened is that individual channels have had seperated streams pulled out of alignment and that makes it impossible to tug them back where they should have been because obviously, each channels waveform does not match each other due to individual channels discrete effects.
so, I had to redo it from scratch. that is now finished.
in the meantime, I have also tweaked a few more scenes, spotted a few errors that had slipped through the net and also came up with some more fixes to the final space battle that have been bugging the hell out of me.
I'm off to work now but upon my return in the am tomorrow I will start remuxing the master file etc to cut a new test disc.
cheers
