By the way:
"Since the DC components are calculated by keeping a running total
starting from
the top-left MCU, it is very easy to see how the cumulative value can
underflow
if something gets out of sync. "

It's not what I've read, and it's not what I've coded.
My professor told me that the DC components are calculated by keeping
a running total starting from the first MCU of each row !!
So if this is wrong, this is why I get an underflow!
