[mpeg2] kfir macroblock corruption?

["Jason D. Justman" <justmanj@msu.edu>]

Hi,

I'm running on 2.4.7 (and fixed the videodev problem with the kfir.c to
match the new v4l headers), but am getting some weird problems.  the
system is a p2-266, but should still idealy be able to handle this
process. I have a netstream decoder card, and essentally am just testing
the encoding->decoding of the board.  I have taken colorbars into the
kfir card, and then told the netstream board:

playfile s /dev/vide0

so its essentally playing a system stream from the kfir..  now, its NTSC
colorbars, and it looks okay, except for once in a while (every one or
two seconds), i see what appears to be a single macroblock being
corrputed.  It has a tendency to be at the high saturated (the I & Q of
the bottom left hand corner).  I then just cat'd to a file, and played
it in a mpeg player, and i still see the same corruption occuring.  Does
anyone have any suggestions?

Thanks,
Jason
