Please try a lower vbitrate and vrc_maxrate. I have found that even with
vrc_maxrate=9800, the peak bitrates are sometimes (much) higher than
9800 kbps (you shouldn't let it happen since such bitrates are not DVD
compliant anymore, even though the newer players are generally able to
play such files). A safe combination would be vbitrate=8000 and
vrc_maxrate=8600, this should make the bitrate stay within the allowed
range.
