Changes:Fix attempt for 1399; if it doesn't completely correct the
multichannel corruption problem (encoder only), then it is a necessary
part of the fix.
(The encoder was accidentally collapsing the redidue bundle to remove
silent residues twice, potentiall causing corruption the second time
if a preceeding channel was silent)
