this line is suspect in log:
ivtv0: Stream decoder MPG: status 0x0118, 100% of 1024 KiB (16 buffers) in
use

it's possible to raise buffers?

also the "good" mpeg have a log with 93% of buffers used
ivtv0: Stream decoder MPG: status 0x0118, 100% of 1024 KiB (16 buffers) in
use

in both cases i ran this command: v4l2-ctl -d /dev/video16 --log-status
(after an mpeg file was send to /dev/video16 of course)

You may also wish to set some debug flags when loading the msp3400 and
