i can rule this out, because although i used both a dvdr and cdr drive 
for burning, both cds were read back in using the cdr drive.

any differences must have occured during burning. but since i used the 
same toc file and disk-at-once mode, it's unlikely that the lead-in got 
interpreted differently in both drives... but you are right, this being 
a live cd, i used pre-gaps and non-silent gaps extensively - i'll 
investigate some more along those lines.
