	there's a VOL header re-inserted just before the
	I-frame #162. Then the next (P) frame #163 starts
	b0rkenin'... Have some default values been assumed
	while re-emitting a VOL-header? (fcode?)
	Also: the sequence ("The Curiosity Company") just
	before the bug is blinking. Is it intended? And
	the very last frame #161 of this sequence, just
	before the bug has a strange superimposed "ghost"
	on it... 
	Also, ffmpeg says, before the bug:

slice end not reached but screenspace end (156 left 17D7C5)bits/s   
concealing errors
header damaged

	and then the quick brown fox jumps ... etc...
	Could this be an alignment problem?

	bye!
