So can anyone else please verify that the info in this post is correct? Mallwalker do you know for sure?

Darth Mallwalker, do you have plans to rip the audio of the JSC?
Here's what happen whenever I try it.
Up until now all the ones I ripped had two seconds of blackness at the start, or else a LaserVision bumper on each side.
But JSC is different. On JSC the movie start at the very first frame on each side (only Side1 has a bumper).
This example show ROTJ Side5. Other JSC sides are quite similar in that regard.
These are several 'takes' from the same recording session:
As you can see, they do not begin at the same byte each time.
The track on top looks most complete of all; it starts soonest.
While the tracks below it are missing at least 25 samples in the shaded region.
Maybe the top one is missing some samples itself? But how many?!?
Once in a while, usually after a 'cold start' I'll get this:
Here the track on the bottom is missing ~17ms, which happen to be the duration of one field in the NTSC stream.
I guess it's like setting the needle on a phonograph and missing the first notes of a song.
I can avoid that situation by spinning the motor first -- that is, leaving the player in Pause mode, or single-step mode, with the motor spinning, then press Play.
So that second pic isn't really a problem, just a curiosity.
However the first picture still bothers me a lot.
How can I be sure I'm getting all the samples?
Or less optimistically, How can I measure how many samples might be missing?
I'd be reluctant to post something like that on Usenet. Would need a BIG disclaimer...
I wonder if collaboration with schorman13 might shed some light? After his JSC is delivered, maybe he'll record the first few seconds of ROTJ Side5 (or any other JSC side really) so I can compare with mine. I would appreciate help.
