I think your right. I'm not sure what a JVT NAL sequence is, but the problem
seems to be in mplayer's demultiplexing. If I demultiplex with 
"xport Transport Stream Demuxer 1.01", everything works. If I demultiplex with
mplayer, it doesn't. Do you know who at mplayer I should send this report to,
and if they have access to the upload directory with the sample? I'm including
my detailed tests below and thank you for testing out this bug. 


'ldecode' below is, I believe, the reference decoder. It was built
from a zip file jm14.0.zip. I believe this is the reference decode
from http://iphome.hhi.de/suehring/tml/)

'xporthdmv' below is "xport Transport Stream Demuxer 1.01"

'ffplay' is an older version based around:
FFmpeg version SVN-r13582, Copyright (c) 2000-2008 Fabrice Bellard, et al.
  libavutil version: 49.7.0
  libavcodec version: 51.58.0
  libavformat version: 52.16.0
  libavdevice version: 52.0.0
  libavfilter version: 0.0.0

~/camcorder/mplayer/mplayer/mplayer is SVN mplayer updated to r27442 from a few
days ago.

///

## This is broken and ldecod errors out with "mb_qp_delta is out of
## range" Only about 4 frames are generated and playback ends after
## playing them.

~/camcorder/mplayer/mplayer/mplayer -nosound -dumpvideo /tmp/HF100_trunc.mts 
./ldecod -i stream.dump -o /tmp/foo.yuv
mplayer /tmp/foo.yuv -demuxer rawvideo -rawvideo w=1440:h=1080 -aspect 16:9



## This plays flawlessly; xporthdmv outputs bits0001.mp{v,a}

./xporthdmv -hn /tmp/HF100_trunc.mts 1 1 1
./ldecod -i bits0001.mpv -o bits.yuv
mplayer bits.yuv -demuxer rawvideo -rawvideo w=1440:h=1080 -aspect 16:9


## This uses the bits0001.mpv from xporthdmv above, and plays
## flawlessly, with no bugs on the first few frames or the large
## problem 8 seconds in. This version does warn noisly about 'PAFF +
## spatial direct mode is not implemented', but plays fine.

ffplay -f h264 bits0001.mpv


## Also uses bits0001.mpv from xporthdmv. Plays flawlessly, but
## complains about 'B picture before any references, skipping' on the
## first 4 frames.

~/camcorder/mplayer/mplayer/mplayer -demuxer h264es  bits0001.mpv -fps 30
